LabView 2010 application runs twice as slow in Windows 7

When our company mandated the replacement of Windows XP PC's, my LabView test application that was compiled in LabView 2010 runs over twice as slow on a Fujitsu Esprimo E710E86+ machine. The application uses a GPIB USB - HS adapter to control an HP 4285 Impedance analyzer whose signals are switched to it using two (2) SCXI chassis that contains five (5) SCXI-1193 switch modules. This chassis uses the USB-1359 communicator.
On the Windows XP machine that is being replaced (a Dell Optiplex 960), a typical set of measurements takes around 40 seconds to complete. The new Windows 7 machine takes about 100 seconds to do the same set of measurements. Has anyone noted this increase in test time???
Thank you.

Hello Rod,
Before updating to LV 2013 I'd recommend isolating what components are causing the slowdown or at least trying to eliminate some of the variables - right now there's a new PC, new OS, new physical connections, and perhaps even new hardware, so figuring out which of these is causing the slowdown should be the first order of business. I've seen issues simlar because USB devices were switched around to different (built-in) ports on the same machine.
A few things to check:
-What does this application do? Are you doing any intensive data manipulation or is this mostly a call-and-response type application?
-What does your system resource utilization look like on the two machines? In either case, are you using more or less RAM on one machine or railing one or more CPUs?
-Do you see the same sort of performance hit on a Windows 7 installation on an Optiplex or similar machine?
-Did you change drivers when you upgraded to Windows 7?
-What NI driver version(s) are/were you using?
-Does this application log data data to disk or perform any network operations?
-Have you attempted recompiling the 2010 executable on "new" hardware? The LabVIEW compiler will optimize for the platform it is being built on and it seems highly likely that the Dell and Fujitsu machines have different processors. As a note I've never seen recompiling in this fashion result in a 100%+ speedup.
-Have you taken a look at the machine's I/O traces to see how long the acquisition itself takes?
-Have you tried moving the USB connections to different ports? Most desktop PCs nowadays have one hub on the front and one on the back of the machine, although I'm not familiar with Fujitsu desktops. If the adapters you are using or anything else on the machine is forcing a USB 2.0/3.0 port to 1.0 or something this could be a factor.

LabVIEW 2010 - applications and RTE question

Hi,
I'm currently using LabVIEW 2009 and my company is upgrading to 2010, and I had a few questions about building applications and running them on other computers after we make the switch.
1) Will computers that only have the LabVIEW 2010 Run-Time engine installed be able to run applications built with LabVIEW 2009 (and earlier)?
    1.1) If not, will we have to rebuild all our existing programs to use the 2010 RTE?
2) Vice versa, will exes built in 2010 be able to run on computers that only have the 2009 RTE installed?
    2.1) If not, is there an easy way to downconvert programs written in 2010 so that they run on the 2009 RTE?
    2.2) Will we be able to use any of the new features in 2010 (like network streaming, export graphs to excel) if we downconvert to 2009?
3. If we rebuild some applications that were originally written in 2009 will we need to install the 2010 RTE on the target computers so they can run the new version of our application?
Thanks!
-Nick
Solved!
Go to Solution.

2.1) Yes, Save for previous... and rebuild the application in LV 2009.
2.2) No because the new features are not present there.

Sine the upgrade my Apple TV runs twice as slow when playing movies off my computer? What gives?

Just as I said in my heading. Since I got the upgrade my Apple TV has been running slower..much slower. When I try to play movies on my compoter. It is at least twioce as slow and takes trwice as long to play on my Apple TV. Can't figure it out...

That typically indicates a network issue. Power cycle the ATV and router.

SQL linked server twice as slow in Windows 7 as XP

We have a transaction based synchronization from SQL Server to Oracle, i.e. both must commit or rollback in one distributed transaction. We achieved this using MSSQL Linked Server using the Oracle Provider for OLE DB and triggers running openquery for speed.
The SQL Sever 2008 was on XP (doesn't need a server) and the Oracle 11g was on Red Hat 5EL. In testing from the first trigger firing to the last trigger finishing, a save test took ~11 Seconds, not perfect but acceptable. Yet when we moved to Windows 7 this time rose to 19 Seconds.
We contacted Microsoft support and they seen to thing it is a multi platform issue. So to prove them wrong we created an oracle DB on a Windows 7 system and ran the tests again, same issue. They will not look into the issue without us paying for premium support at an hourly rate, due to the Oracle DB. So we created one more test environment to try to prove it was a Microsoft issue and not an Oracle driver issue we created 2 SQL servers and ran tests to see if we got the same issue. We got the following results, which seems to point the finger at the Oracle OLE Driver on Win 7:
Windows XP sync to Windows 7:
SQL Server to Oracle = ~8 seconds
SQL Server to SQL Server = ~6.5 seconds
Windows 7 sync to Windows 7:
SQL Server to Oracle = ~19 seconds
SQL Server to SQL Server = ~5.5 seconds
Has anybody else found this issue and if so have they found a cause?
We Have run NetMon and analysed the results and the packets seem to take twice as long in Win 7 as Win XP. This seemed to point to a network issue, but does not explain why 100% Microsoft is faster when synchronising Win 7 to Win 7, as opposed to Win XP to Win 7.
I get the feeling the issue lies somewhere in the changes that were made by Microsoft in Vista in the networking protocols and configuration, causing a side affect in the OLE Driver. It could be that the driver works, but needs to be tuned with the new networking protocols from Microsoft.
We have tried countless network settings, even the ones suggestions from MS Support made no difference at all.

Corrected a couple of types

Hi Greg,
Thanks for the answer, sorry for the late reply, I was away for Easter.
What we have done is to alter the triggers to record their names, start and end times to an SQL Server table. I delete the contents of the table then run a test and run several queries to analyse the trigger data. the difference between the min start time and the max end time is how we get the total time. We run many queries over the data. I can send you the table DDL and some test run results DML, as well as, the queries I use to analyse the results.
On top of this test we have run Microsoft's NetMon to analyse the network traffic and there it is clear that the packets take roughly twice as long in Win 7 as in Win XP, both in 32-bit and 64-bit OS versions. I know there has been some major network changes after Win XP and Microsoft are convinced this is an Oracle issue. The same OLE Driver is used for both Win 7 and Win XP OS's (excluding the one for 32-bit and one for 64-bit) and my guess is something needs to be tuned for the networking in Win 7. We have really tested this so much over the last 2 months and tried all kinds of network setting tuning in windows but nothing has worked at all.
After creating an SQL DB to act in the place Oracle DB, the same issue was not present, so it really is a heterogeneous platform issue. In fact if the sync is SQL to SQL it is faster in Win 7 not slower.
If you would like any of the results of our testing to see if you can spot the issue, you would be welcome.

LabVIEW crashing when running NI-DSP VI on Windows XP

I am in the process of upgrading a software application from LabVIEW 3.1 on Windows 3.11 to LabVIEW 7.0 on Windows XP with NI-DAQ 7.2. The hardware has been replaced, the relevant hardware change here is from the AT-DSP2200 to the NI-4551.
The source code uses the NI-DSP libraries to control the DSP2200. I can't find any equivalent in the new LabVIEW (and have assumed that there is none, this is all covered in the MAXX now). The source code has been convereted to LabVIEW 7.
When the source code is opened on the Windows XP machine LabVIEW crashes. I've traced to cause of this crash to the NI-DSP code. Whenever I try to open any VI that contains the DSP code it crashes LabVIEW. I think the problem is the CNI call
inside the DSP library. When I try opening the source code on a computer that doesn't have the NI-4551 installed there are no problems.
What is the upgrade from NI-DSP to? Is there a direct mapping of NI-DSP functions to equivalent NI-DAQ ones? How is it that having the hardware plugged in causes a crash even though it shouldn't be accesssed until I run the VI?
Any help would be appreciated.
Thanks.

Hello EborLance,
The NI-4551 can use either NI-DAQ or NI-DSA as the driver. If you only have NI-DAQ installed, any program that uses the NI-DSA functions may be crashing.
There is no direct mapping of NI-DAQ functions to NI-DSA functions but you can download and install the NI-DSA driver from the website. Current DSA Drivers
Once you have installed the NI-DSA driver, you should see the functionality you were previously used to and your program should run.
Thanks,

Application runs but not as a Windows service oracore

I have a weird problem and I was hoping somebody might be able to help me. I have an application that we developed that uses an Oracle database. The application can be run in user mode(double clicking on the file) or as a Windows service. We have always used the Oracle Database client to connect to the Database in user mode and it has worked. Using the same configuration we were able to run our application as a service and it has always worked. The problem now is that if we use a newer Oracle Client (>= 10.2) it will not work as a service. When I say it doesn't work I mean that the application never starts and the Windows Event Viewer log states an APPCRASH in oracore10.dll or oracore11.dll.
It doesn't seem to matter which database we use, 10G, 11G, because if we use the 10.1 version of the Oracle Database Client to connect to these databases it works. However if we use any client>=10.2 the application crashes.
Any suggestions?
Edited by: 945875 on Jul 11, 2012 1:45 PM

So I stopped any Oracle windows services that were running, deleted the only oracle directory on the machine, and reinstalled 11.2 client. The same results occur, I can connect to and start my application in user mode but not as a service. I checked the version# of OCI.dll, 1 instance of it on the machine, and it does state that it is version 11.2.0.1. The setup I have is:
Machine 1: Server 2008 R2
Oracle 11g database
Oracle 11g client
my application
Machine 2: Windows 7 64-bit
Oracle 11g client
my application
I get the exact same results if I try to run my application on the same machine as the database (machine 1) or across the network (machine 2).
I've setup the connection using Oracle Client's Net Configuration Assistant, added the Local Net Service Name Configuration, and am using TCP. At the end of the Local Net Service Name Configuration I get "Success" when talking to the database.
Thank you for any help you might be able to provide.

Why is running Elements 8 slower on Windows 7 than XP?

I am afraid this is query is a bit long, but I have tried to provide all the
info I can ....
THE PROBLEM
My old PC died, so I bought a new PC to improve my video processing speed, and also move off Windows XP.
- I installed the same copy of Adobe Premiere Elements 8 on both PCs.
- I applied no updates (on either machine) as the original versions works fine (on XP - why fix something that isn't broken)
- I changed the preferences to stop background rendering (due to data volumes -
same on old PC).
- I then copied the project file (.prel) from the old PC to the new.
Having set up the new PC, I carried out a benchmark test in Premiere Elements 8.0 converting the same 4-hour long HD file from M2TS to MPG on both PCs.
It was 4 times slower on the new PC !!!!
I then tried out another video conversion program (to demux MPG files so that they can be edited in Premiere) and that was 30% faster on the new PC.
In the Premier test the original file was on a 6GB/s 3TB disk drive with the output file on a 6GB/s 2TB drive (which also has the Windows system and Adobe cache files).
- Both processes ran identically without errors. In fact the output files were almost identical (one was 12 685 358 KB, the other 12 658 402 KB). I ran MediaInfo on both output files and it summarised them as identical in terms of codecs, size, etc, etc.
- On the old PC, CPU utilisation is usually around 90%, on the new one it is closer to 50%.
- Disk and memory utilisation are not limiting factors.
Can anyone help me finding out why the new PC is so much slower than the old?

BACKGROUND
I have a very specific use of Premiere (for research purposes):
- I have 2 HD video Sony XDR160E camcorders monitoring bird nests 13 hours per day.
- Each camera generates 160 GB data per day on its internal HD.
- File sizes range from 20 GB (smallest) to 160 GB.
- I download the files from the camera to disk using the cameras download facility.
It is then that I use Premiere.
- I open a project that has the exact specs of the camera's output.
- I open the M2TS file in Premiere, drag it onto the sceneline.
- I do not view the file but immediately share it using a preset that matches the requirements of my MVIX PVR.
This bit is not relevant to the problem per se, but provides background info:
- I then copy the file onto the PVR decoder.
- I view the file through an MVIX PVR which allows viewing at 32x speed with minimal data loss.
- I will then identify activity periods (which may be only 5 minutes per day).
- I use the camera's editor to extract the relevant clips keeping all the camera metadata intact.
- After that I may use Premiere again to create illustrative montages.
CONCLUSION
Does anyone have a clue as to why I am having this problem? (it is not an error per se)
- The obvious differences are the operating system, the graphics card and the disk allocation unit size
- It may well NOT be a Premiere issue, it may be Windows 7 Pro that is causing the problem.
- I assume that the graphics card is irrelevant as I never actually view the video in Premiere (in this scenario)
- Could it be that Adobe cannot handle the 64k disk allocation size?
- Is there some special setting in Windows 7 that I need to enable that wasn't required in Windows XP?
- Is there some special setting in Adobe that I need to enable when running in a 64-bit environment?
Or is there something else I am missing?
Any help would be really appreciated - it could take weeks to try out all the various combinations to identify the problem.

Thanx for your insights. I do not have the disks partitioned (except the system disk, I always like to keep the system files separated from the 'user' files to make backups simpler).
I suspect you are right that upgrading to 11 would speed things up, but I still suspect there is something more fundamentally wrong in my Windows 7 set-up - my guess is that upgrading to 11 might double the speed of processing - but that would still leave it 50% slower than on the old machine.
My first step will be to run all the patches on 8 - but not for a few days. We are expecting 3 or 4 days of thunderstorms (normal for this time of year in South Africa) and my UPS hasn't the battery life to keep going during an upgrade cycle.

Labview 2010 run-time engine silent install

I am having trouble with installing the run-time engine for LabVIEW 2010 with the silent option.
I am using the minimum version of the run-time engine.
Before I used the LV7 run-time engine. Then I could install it silently using LVRunTimeEng.exe /qb!
In LabVIEW 2010 the run-time engine is no longer a single file but a directory that contains the installation files. There are two files that can be used to launch the installer Setup.exe and LV2010runtime.msi.
Setup.exe does not seem to accept any command-line arguments. LV2010runtime.msi however accepts the command-line arguments and can be installed silently.
Now my problem is that I am building a windows installer using a third party application and it is only possible to launch exe files after the installation completes. Before I could launch the LVRunTimeEng.exe /qb! to install the labview 7 run-time engine but now when I have upgraded to labview 2010 I cannot do the same for Setup.exe.
My question is if it is possible to use the Setup.exe file to install the Labview 2010 run-time engine (minumum) silently?

Setup.exe runs a number of other .exe files during its execution. This article looks like it will allow you to run setup.exe silently by supressing all messages and windows:

Application running slowly under Hyper-V (factor of 100 times slower)

I have an application running in a non virtual Windows Server 2008R2/SP1 environment. It processes about 60,000 records from an indexed file (about 20MB in length) in about a second running in that environment. I want to move the application
to a Hyper-V virtual server also running Windows Server 2008R2/SP1. When I do so, the application runs, but processing the same file takes almost 2 minutes.
The application is the only thing running in the virtual machine and the virtual machine is the only VM running on the physical box. The VM is configured with a single processor, 2048M of fixed (not dynamic) memory and a fixed size disk of 255GB.
There is no network traffic so the single network connection is not used. The physical machine is a quad core with 8GB of memory and two 1TB drives that are less than 1/4 used in each case.
Now for the weird part. The application runs from the command line. If I start it and do nothing else, it takes about 2 minutes to complete its process. But, if I start the application, switch focus to another window on the virtual
machine then switch back, the process completes immediately upon switching back to the command line window.
Any thoughts?

The VM is configured with a single processor - The physical machine is a quad core
Do you mean the physical machine that was running the application has a quad core processor? If not, what did the physical machine running the application actually have? Is the application multithreaded so that it can make use of multiple processors?
Did the application in the physical world have OS and data on the same disk or on different disks? Did you run this application shortly after you started the VM, or did you let the system quiesce a bit? Did you measure performance on the physical
under the same sort of conditions? Are you running from a cmd window or PowerShell? (Your comment about clicking away and coming back brings to mind things I've seen with PowerShell) Does it run quickly on a second instantiation, or does
it run poorly every instantiation?
Determining performance requires a lot more information than what you provided.
I always assign at least two virtual CPUs to any Windows Server VMs. There are enough system processes running on the box that two processors will almost always benefit the workload. Also, it it not uncommon that the first run of an application
shortly after a machine has started will never perform as it will after a machine has settled in. This is why every benchmark worth its salt will start the benchmark and let it run for a few minutes before they actually start measuring.

Is 120fps movie going to be twice as slow away from Flash ?

Flash CS5,
Powerpoint 2007
Why would 120fps swf be running twice as slow as its design speed in conversion to wmv, as well as when run in powerpoint ?
This seems like a fundamental issue now and not just Msoft software issues, though WindowsMovieFile is Msoft, having said that !
Perhaps it is Msoft at fault ?
I could try converting to avi.
Any suggestions what video format to initially convert to to retain 5 sec play time ?
I have trialled an swf to wmv converter, the swf also runs twice as slow in that prog, as well as when run in powerpoint. Is 120fps unable to be used in the world of PC’s ?
Real movies use 25fps, the human eye cant see 1/25 second changes in frames, I have a 767px tall stage and cars on it travelling at 12 mph, I cannot use less than 120fps as the pngs are jerky, I would have to lessen the frame length of the movie to retain the travel speed, and the pngs would have greater distance to travel per ‘tick of the clock’, which gives jerkiness, as it would appear that flash as it progresses artwork to each frame moves fwd then pauses then moves then pauses. One could have fluid motion across frames, it would still be eating up so many frames per second, one could have 12fps and 12 frames and a smooth 1 second travel, if motion was uniform, it’s the way flash handles the progression it seems.
I was hoping that this progression would be smoothed out when made into a movie, but its running twice as slow so no advantage there.
Envirographics

When you export a flash movie to a video format, that video will be set to the defaults for frame rate, size, compressor, etc. You can change these settings in the options window after you select the output file type. Have a look in those settings and see if you can get the output that you need.

My 27" 2010 iMac has recently began freezing and movement on the display is molasses slow. We have 500 gigabytes available and no applications running and the problems still persist. Any advice?

IF your system is running extremely slow with no applications running other than Finder then I'd suspect a failing HD or you have a runaway process somewhere. Open Activity Monitor (Applications - Utilities - Activity Monitor) and look to see if you have any applications taking a large %CPU, if you do that is your problem. To test the HD run Apple Hardware Test, please read:
http://support.apple.com/kb/HT1509
to learn how to run AHT on your machine, also run it in EXTENDED MODE so it does the most complete test. If no errors are found after the first pass run it another 2-3 times to be thorough.

My MacBook Pro 2010 is running very slow...what to do?

My Macbook Pro purchased in 2010 is running extremely slow. I would love to trash a bunch of stuff but whenever I try to do that, it freezes.
What to do? Is there a simple thing to do to number one... get it to work faster and two... how to stream down everything on it.
MH

First, back up all data immediately, as your boot drive might be failing.
There are a few other possible causes of generalized slow performance that you can rule out easily.
Reset the System Management Controller.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Check your keychains in Keychain Access for excessively duplicated items.
Otherwise, take the steps below when you notice the slowdown.
Step 1
Launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
Step 2
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

I tried another machine, 64 bit of course, as I want to deploy my application on a 64bit PC, but still got the same problem.
This other machine was from HP, iCore 3 (4 CPUs) 2.2GHz, 4GB RAM and running Windows Professional 64 bit.
Now as I see it, it could be a Run-time environment mis-match error.
For this I tried installing a 64 bit LVRTE from NI, but still no sucess.
I checked DEP, for all 3 PCs and it was set to the following
Turn on DEP for essential Windows programs and services only (first option).
I am confused. I can not find a solution for this and it is really frustrating.

But I am assuming that when I make the installer, the 32-bit Run Time Engine is appened with the installer, as show below
Since from the picture you can see its including the support installers from '\Program Files (x86)\'
The application runs queries to fetch data from database in SQL server 2008, and for that I am using a Microsoft SQL Native Client 2008 R2 64 bit ( this is the only version that installs on either PC, even the one on which I developed my LV Application).
I am not using any driver, only toolkits for reports - and for that I un-checked the "Remove unused polymorphic VI instances" when making the executable, otherwise LV throws up an exception that share variable are not being included.
Yes I did reboot every time after I ran the installation.
Still getting the same error.

My mbp (mid 2010) is running extremely slow after installing some mavericks updates on May 22nd.

My mbp (mid 2010) is running extremely slow after installing some mavericks updates on May 22nd. Earlier I thought this behavior is due to spotlight indexing but it finished after 3 days. I deleted all caches from library. But no luck, still running extremely slow. I checked activity monitor for cpu usage, it shows above 90% is idle. The memory usage always shows PM - 4 GB, Memory Used 3.96 GB, VM - 4 GB, Swaped used 0 bytes, App Memory 1.82 GB, File Cache 1.44 GB, Wired Memory 480 MB.
Thanks in adavnce for help.

Was it the combo updater that was installed or the OS X 10.9.3 update. There is a difference.
MORE INFO ON WHY RUNNING COMBO FIXES ISSUES
Apple updates available from the Software Update application are incremental updates. Delta updates are also incremental updates and are available from Apple Downloads (software updates are generally smaller than delta updates). The Combo updates contain all incremental updates and will update files that could have become corrupted.
Combo updaters will install on the same version as they're applying--no need to roll back or do a clean install. So if you think you've got a borked 10.8.4 install from a regular update, just run the 10.8.4 Combo Updater on that system.
"Delta" updaters can only take you from one version to the next. For example: 10.9.1 to 10.9.2. If somehow the 10.9.2 is missing something it should have, and that something isn't changed between 10.9.1 and 10.9.2 it will still be stale after the delta update.

Problems distributing application using Imaging Source USBCamera and Labview 2010 - Imaging Source sdk required?!

Hi
I've been having trouble with the Imaging Source camera we own when trying to build applications.
Everything works perfectly on the dev PC with appropriate sdk installed.
When I move to building the application (no errors) and deploying it to another PC the activeX control used to interface with the camera does not appear.
Instead I get 'Control could not be loaded' in red text where the control should be.
As far as I can see the activeX component itself is correctly installed on the PC.
If I install the IC Imaging Control sdk the application begins working correctly.
If I uninstall the sdk from the dev PC I get the message about needing a license if I attempt to add the ActiveX control afresh to the program (via the activeX container)
I've posted on the Imaging Source forums and they suggested I try here.
ORIGINAL POST ON IMAGING SOURCE FORUMS:
I'm using a DMK 41BU02 with labview 2010 + IC Labview extension.
The activeX interface for the camera works fine until I deploy it to a PC that does not have the IC Control software installed.
All I see is a 'Control could not be loaded' message where the activeX box should be.
I've installed VB6 redistributable to the client PC so I know the activeX workings should be present on the PC.
If I install IC Control onto the PC the program starts working correctly!
Has anyone compiled software with Labview 2010 successfully?
Is there a trick when creating the application/installer spec?
Thanks in advance

This is correct. I suppose, the LabVIEW setup creating system does not automatically add the used DLL in the "user.lib" directory of your LabVIEW installation path. What does the LabVIEW support say about this, especially in relation to ActiveX controls, that use the Microsoft licensing mechanism?
The dll he mentions is packaged into the support folder in the application spec.
I have also manually copied the dll into the location referenced by the software (Labview 2010\user.lib\xxxx.dll).
This made no difference.
I've got no experience building these kind of thing into applications so I cannot tell if it is caused by a mistake I've made or Labview or if the Imaging Source softwares have done something wrong.
Many thanks in Advance

Dan,
I think I might have a solution for you and others who need to include the imaging source active-x control in a deployed executable program.
I solved this problem by creating a project that included the dlls and .ocx files required for the Active X Control (these files are in a folder is created once the IC Software is installed C:\Program Files (x86)\Common Files\IC Imaging Control 3.2) and an executable that registers the Active X Control after the main program is installed.
The simple vi that registered the .ocx control for me upon install of my LabVIEW executable was called RegisterActiveXCtrl.vi. All it does is calls the regsvr32 with the path of my .ocx file.
I bundled my main program PCDemo_Stratom.exe and RegICActiveX.exe into an installer and set the option to run RegICActiveX.exe at the end of installation.
The installer must be installed with administrator rights to get the RegICActiveX.exe regsvr32 call to work.
Hope this helps you/others in the future!
Dan A

LabView 2010 application runs twice as slow in Windows 7
