Instrument I/O assistant in runtime engine

Hello,
I currently use the Instrument I/O assistant in some of my VIs to communicate with an Agilent network analyser using SCPI commands. This works fine, and I am able to do everything I want to do (on my desktop which has LabVIEW installed).
I would like to be able to run my VIs on a laptop which does not have LabVIEW installed, using the free runtime engine. I have successfully been able to do this with several VIs that do not contain the Instrument I/O assistant.
However, I can't get any VIs that contain the assistant to work on the laptop. I have verified that the connection between the laptop and the network analyser is OK in MAX, and all the device numbering and addressing is the same on the laptop as it is on the desktop. I have even been able to get individual blocks such as "GPIB Write" to work on the laptop.
Any ideas would be greatly appreciated.
Cheers,
Dan

What version of LabVIEW are you using? For quite a while, you have had the option of creating an installer. This is the recomended way to distribute an exe. Prior to 8.x, you could include the LabVIEW run-time. Since 8.x, you have had the option of creating an installer that included hardware drivers such as GPIB, DAQmx, NI-VISA, etc. You could also download the VISA run-time. The full version of VISA should also be included on the CD you got with the GPIB board. Some of the GPIB CDs did not automatically install VISA but you can always stick the CD in and manually select it for installation.

NI Developer Suite 8.2 / LV Runtime Engine 8.2 vs 7.1.1

I have NI Developer Suite 8.2 and have installed LabVIEW v8.2 from it onto my development computer. I have converted a LabVIEW 6.1 application to 8.2 and am now setting up an installer build for the application.
When setting up installer build properties, I find NI LabVIEW 7.1.1 Runtime Engine, NI LabVIEW Run-Time Engine 8.0.1, and NI LabVIEW Run-Time Engine 8.2 listed as additional installers that can be included in the build.
Wanting to use the latest and greatest for my application, I have selected Run-Time Engine 8.2 for inclusion in the installer.
Upon testing the installer, I find Runtime Engine 7.1.1 installed, not 8.2.
I checked the development computer (Control Panel->Add/Remove Programs->National Instruments Software) and found only Runtime Engine 7.1.1 installed. I then uninstalled LabVIEW 8.2 and reinstalled it, hoping to be able to specify which runtime engine to install, but there is no option in the installation process for runtime engines.
My question is: what happened to runtime engine 8.2? Why can't I get it installed on my development computer? If it doesn't exist, why is it listed in the installer build properties as an installer that can be included? Is it vaporware?

Hi Igk,
On your development machine, the LabVIEW RTE 8.x will not appear in Add/Remove Programs because it is an invisible MSI Installer. The installer is invisible because other applications (LabVIEW Development environment, for example) are dependent on the RTE. Uninstalling the RTE would cause problems for all the other programs with dependencies, so the option to remove it is not there. If you uninstall all the programs that depend on the RTE, the RTE will be uninstalled with the last program. You can see in the attached image that I don't have LV RTE 8.0, or 8.0.1, or 8.2 in Add/Remove Programs, but it is listed in MAX Software.
If you run this LV installer on a clean PC(without the LV development environment), I havn't tested for sure, but because the application installed depends on the RTE, the RTE still probably won't show up in Add/Remove Programs (but your application will). You can verify the RTE's existance by checking the <Program Files\National Instruments\Shared\LabVIEW Run-Time\8.2> directory and verifying the lvrt.dll version is 8.20.x.xxxx. Also, when the application runs, you will know the RTE exists. Also as TonP mentioned, you can use MAX to verify its installation.
As a side note, I would generally avoid running LV built installers on a development machine that already has LV. Installing the RTE (or any other NI installer) from a LV custom installer will change its installation source stored in the registry from the LV CD where it was originally installed from to the installer that you built. Future repairs of the RTE will then look for this custom installer rather than the original source. If that installer disappears or changes, repairs or uninstalls become more difficult. I usually set up a test machine to test my LV built installers.

Cannot Install LV Runtime Engine 7.1

HI,
Some of our users are having unusual installatiion problems while
installing the LV runtime Engine 7.1.1 on win2k. Our users have
installed another application recently and in that process the LV
runtime engine was removed from their computer. So, they tried to
install the runtime engine(downloaded it from NI website) again but couldn't becuase they keep getting
the message that they are not logged in as administrator. We logged in
as admnistrator and tried installing the runtime engine again,
but the error keeps occuring and is not allowing us to install. I
searched the NI discussion forums and the Knowledge base to find
answers but did not see any that match our problem. From some of the
posts I suspect it has got something to do with Microsoft hotfixes and
windows upgrades etc.
If anyone else had seen this kind of behavior and has found a fix,
please share it with us. Any help will be greatly appreciated.
Thanks Ahead

Hello!
This is an unusual problem. I would first go through the add/remove
programs through control panel. Loate the "National Instruments
Software" item and select "change". See if any LabVIEW
components are there and slect to remove them. This will completely remove the
LabVIEW components. Then attempt a reinstall of the runtime engine.
If this still causes problems, you may have deleted the old LabVIEW runtime
engine in an unusual way which is interfering with later installs. If this
is the case, there are some other methods that we might be able to use to
uninstall fragments of NI software. Removing the software does not fix
the problem post back and let us know!

Unable to install LV Runtime Engine 7.1.1 with LabVIEW Professional 8.5.1

I installed LabVIEW Professional Sys. for Windows (XP) 8.5 and then the 8.5.1 update. Somewhere in the original installation, LV Run-time Engine 7.1 was installed. But I need LV RTE 7.1.1. So I attempted to install RTE 7.1.1. Problem: The LV RTE installer aborts with the following message:
"Installation aborted. Newer version already installed."
Why do I need 7.1.1? I must run some commercial LV executables that were compiled with LV 7.1.1 and will not run under 7.1.

Well, I have to correct myself. MAX indicated that LV RTE 7.1 (not 7.1.1) was installed. My complied LV app indicated that 7.1.1 was not installed. I checked Windows Add New Programs and selected "National Instruments Software" I found that LV RTE 7.1.1 was, in fact, installed. So I selected LabVIEW Runtime Engine 7.1.1 and clicked Repair. After rebooting, My app works correctly. Again, MAX incorrectly displays LV RTE 7.1 (not 7.1.1). My app works, so I don't care.

Runtime engine files 8.2

Hi,
Since most users of my written program are users with "restricted right" acounts under Windows XP I copied the Runtime engine files of LV7.11 manualy by copying the
"Program Files\National Instruments\LabVIEW 7.1\Shared\LabVIEW Run-Time\7.1" files to the harddisk and run a build executable from that directory. Since this application looks in its own directory for support-files this worked fine for LV7.1.
Last week I converted my program to the LV8.2 version. When I tried to copy the RTE8.2 file in the same way as I did before, the program would start-up. It asks for a NIINI32.DLL file. When I include this file it does not return any errors, but the program doesn't start. Can anyone tell me whether their is a different way to run a exe-file build by LV-application builder by copying files manual in stead of running the RTE-installer?
Thanks in advance,

I know that NI did the run time engine to minimize space when installing multiple application. But i'm agree with you, we should have another way to build executable without the runtime engine. Some people dont know what it the runtime engine and uninstall it. afther that they just cant use the program anymore. The other reason, it that a VI use just some Kbyte and the run time engine that include almost everything, need some Mbyte.
If somebody know, please tell us......

LabVIEW 8.5 - error: M&A Explorer or Instrument I/O Assistant is not installed correctly: what to do?

Dear NI creators and users,
I freshly installed the LabVIEW 8.5 and the default set of device drivers (on a new Windows XP machine), all of which I downloaded as disk images from our university central repository (we have a site-wide license). The first thing I tried to place in my first VI was the "Instrument I/O Assistant" and I got this message: "Measurement and Automation Explorer or Instrument I/O Assistant is not installed correctly. Please install these from the LabVIEW Driver CD." I tried to repair the installation, but no change. The M&A Explorer comes up fine, when I select it from the Tools menu, so I doubt, that the problem is there. Needless to say, the "Instrument I/O Assistant" throws the same error when double-clicked in the template file.
Does anybody have a similar or the same experience? What can I do to solve this problem? Perhaps I should add that the computer with LabVIEW is intentionally not connencted to the internet, so in case the solution involves an update, I would very much appreciate some guidance to an off-line update
Many thanks to all for any helpful remarks.
Daniel

Labview 8 Application Builder and VISA Runtime Engine

Hi,
I am using Labview 8 Application Builder and everything is working fine except for 1 small thing. My program makes use of some of the VISA functions and when I build the application I'm having to include the VISA Runtime Engine Installer as a separate item on the CD to make the .exe file work.
What I would ideally like is for people who want to use the application to run the installer and that all necessary components (including the VISA Runtime Engine) are also installed in the one installation. At the moment they're having to do 2 installations and I would like to streamline this.
Is this possible?

Computer with labview runtime engine (v8.2) cannot find sub-VI NI_AALBase.lvlib:Mean.vi. What do I have to do?

I am trying to run an exectutable on a computer that has the labview v8.2 runtime engine. The error I am getting is: Cannot find sub-VI NI_AALBase.lvlib:Mean.vi. What is the easiest solution?

the matrix,
I would try reinstalling the LabVIEW 8.2 Run-Time Engine. You may also want to try creating a very simple project in your development environment that has a VI with just the Mean.vi, try building an executable and then running it on the machine that just has the 8.2 RTE.

Installer build wants wrong runtime engine

LabVIEW 8.6
Windows XP Pro
When I build the installer for my application, it wants me to have available the install disk from November 2007.
Expanding the list for that disk, I find that it wants the runtime engine for version 7.1.1.
If I remove NI-DMM 2.9 from the 'National Instruments Installers to Include' list in the Installer Properties, the error goes away. The description for that installer indicates it comes from the August 2008 device drivers disk.
At one time I had other versions of LV on the computer. I have removed all other versions, including the directories in c:\Program Files.
My application uses the DMM device driver, so I assume that I need to check the box for the additional installer. I've looked for more documentation on when and why I should select different items in the list, but couldn't find anything useful. Would it be possible for the installer to automatically select those items required and perhaps let me direct it otherwise by choosing fewer or more items?
Bottom line, do I need to select the DMM driver to ensure that my application will run on a computer that doesn't have LV installed?

Hello all,
I couldn't really understand what was doing on in the above questions and answers but from the forum topic I believe I am in right place. I have an issue similar to those desscribed above. I have LabView 8.6.0 installed on my computer but when I run LabView it starts asking for 'NI LabView Runtime 7.1.1'. I tried feeding in the labview 8.6.0 but it doesn't accept it and keeps asking for 7.1.1.
The program used to run fine couple of months back and I then didn't use it for a while and I had other prgrams installed durig this time. And when this month I tried to use LabView it started giving me this trouble. I don't know what went wrong. I installed some ftdi chip drivers also. So, I am thinking if that kind of messed things up.
Also, I have this windows installer message come up sometimes which is not when I open LabView but some other programs. I don't know if this windows installer has to do anything with it.
Whatever the case it is could someone please help me figure out how I can get the right runtime work for my LabView 8.6 and if also possible how i can get rid of this windows installer message. I don't remember the error code right now because it comes up randomly. Next time I see it I am going to save that number. But in the meantime if anyone can help me with LabView 8.6. runtime engine problem.
Thanks,

Running Datasocket in labview 2013 open labview runtime engine 7.0

Hello All,
I am trying to communicate with a COGNEX camera using Labview 2013. I am using Datasocket to read tags from cognex OPC server.
but when I open labview and run the code for the first time. An installer will automatically pop up trying to install labview runtime engine 7.0.
When i cancel the installation datasocket throws an error. Again if i run second time, datasocket works fine and communicate with cognex camera using OPC.
This problem comes everytime I open labview and run the datasocket. I cancel the installer. second time onwards when i run the code everything works fine.
This is actually annoying and i doubt how things will work when i make an executable.
Need help.
Is this due to datasocket version installed... how to resolve this.

Hi phil,
That is interesting that you were unable to find the offending key that the installation is having trouble with. Do you have Administrator privileges on your computer? You may even want to try to log in as the actual Administrator itself to make sure that you have access to all of the proper registry keys. Also, I was going to say that I do think you're right with Windows XP not having the Scanreg/fix function, but there are several free programs that you can download as registry checkers. You may want to try one of those to see if you can find the key and give it the proper permission.
As far as the other part of your question, the Run-Time Engines are very important for LabVIEW to be able to run, but the 7.1.1 Run-Time Engine should not be affecting a LabVIEW 8.2 installation as it will use the 8.2 Run-Time Engine. One thing that you can do is go into your Control Panel under Add or Remove Programs>>National Instruments Software and you can try and repair/modify your Run-Time Engine there. If you already have the 7.1.1 Run-Time Engine on your computer, this is where it will show up so you can make any changes you want. Also, if you go to www.ni.com and click on "Drivers and Updates" on the right, you will be able to find the Run-Time Engine there that you will need, but I would definitely try using a downloadable registry checker first before attempting to change any of the software that is currently on your computer. As stated in the Knowledgebase article, this is actually an error from Windows saying that the registry key does not have the proper permission settings, so I am reluctant to say that downloading the new Run-Time Engine from our website will help much. Please try some of these suggestions out and let me know how they work out for you. Thanks!

LabView Runtime Engine 7.0 trys to install at start up

This just started happening, every thing was fine a few days ago. Now when I click on the LabVIEW desktop ICON it says it wants to install the 7.0 Runtime Engine. And asks for disk#3 Do I need this? Eventually after canceling prompts for a few minutes it loads my lab view and my VIs seem to work fine.
I,m using the 8.6 student edition,
Any Ideas?
Thanks

Solved!
Go to Solution.

Alan,
The lvruntimeeng.msi that you said your program is looking usually resides in your drivers installer folder with a path like this:
C:\National Instruments Downloads\NI-DAQmx\<Your Version>\NIDAQ<Version>-1\Products\LabVIEW_Runtime_Engine_71\LV711RTE
Mine is exactly this path:
C:\National Instruments Downloads\NI-DAQmx\9.0.2\NIDAQ902-1\Products\LabVIEW_Runtime_Engine_71\LV711RTE
The 7.1 Runtime Engine is uniquely named "lvruntimeeng.msi". The 8.0 is named "lv80runtime.msi" and 8.2 is "lv82runtime.msi" and so on. Since we cannot install this 7.1 RTE because you have a more recent version installed, please check the path name described above to see if your 7.1 Run-time Engine MSI is in there. Maybe even run a search to see if it is present anywhere on the system.
If not, we can uninstall and reinstall your DAQmx drivers and reinstall them since they will have each Run-time Engine MSI.
Clearly there has been a file structure mishap and these can typically only be remedied by completely reinstalling the program(s) that initially installed the file(s).

Plugin 1.0.
My appli work very good on my developpement computer, but when I install the
appli on computer with RunTime Engine 8.2.0, NI DACmx 8.3 and NI USI TDMS
Plugin 1.0, I have a error. If I use RunTime Engine 8.2.1, NI DACmx 8.5 and NI

The error is 2500.
How I can use my appli with a run time ????!!
Thanks

Hello,
I suggest you to reinstall everything on the second machine, because what you did seemed to be the right thing to do, you must install the same run-time version as your LV version (what you did at first) and every soft or plugin you VI needs.
I really think it will work... (I hope)

Labview runtime engine plugin problem in Mac OS X

Hi:
We have just recently acquired a macBook Pro and am trying to test some instrumentation modules we have previously developed online for Circuit Theory courses on the MAc platform.
These VI's are installed on lab view server and we have no difficulty accessing them in Windows XP or Vista from a browser either Firefox or IE. Of course the latest version of runtime engine is installed on the pc prior to accessing the vi using remote panel and secondly we have to disable any virus protection software.
I have also installed the 8.5 version of LV runtime engine on the macbook with Leopard 10.5.x OS. I can see the LV plugin with the proper version in the Installed plug in check for the Safari browser. But every time the Remote panel is accessed I get a missing plugin message.
Here is the message:
Safari cannot find the Internet plug-in.
The page “Blackboard Academic Suite” has content of MIME type “application/x-labviewrpvi82”, but you don’t have a plug-in installed for this MIME type. A plug-in should be available on this page:
http://digital.ni.com/express.nsf/express?openagent&code=exck2m&
Do you want to open the page?
The page it suggests is the NI site for the plugin download?
I am really in a corner and donot know what I am doing is wrong? Any help will be appreciated?
Vishnu

I'm not a Mac expert, but it sounds like you are missing the LabVIEW Browser Plugin which is necessary to view remote front panels. That plugin installs with the LabVIEW runtime engine which you can find here. I don't think Safari requires any extra configuration to work with the plugin but it might... let us know if installing the runtime engine doesn't resolve the problem.

Labview trying to find runtime engine when opening up VB6

This is bizarre. I'm not even trying to open a labview program, and I get this error.
when I go to open up VB6 from Visual Studio (Visual Studio 6, Enterprise Edition), I get a pop-up saying that the Labview runtime engine 7.1.1 is going to be configured. A new window then pops up, because it can't find the lvruntimeeng.msi file.
Problem is, I'm using Labview 8.2.
Worse, now my VB6 programs are hanging if I close out of all the installer boxes (it does this multiple times).
UPDATE-4:42PM EST-
I noticed when I went into Add/Remove Programs in the control panel, when I clicked on Change for National Instruments, it says that only the 7.1.1 Runtime Engine is installed. However, I can not uninstall it because another product relied on it. I also downloaded the 7.1.1 runtime engine, but it doesn't install because it says a higher version is already installed. (?)Message Edited by Dauntless on 12-26-2006 03:46 PM

There are some NI programs which were written in LabVIEW and so need the LV RTE in order to run.
Theoretically, the RTE should be properly installed when these programs are installed, but for some reason maybe it wasn't. Maybe one of the NI services running on your machine tries to do something when you're opening VB or maybe your code calls some NI component?
I used to have something similar where for some reason going into certain websites prompted me to insert the LV 7.1 CD so that I can configure the RTE. I think it stopped after doing it one time.
You can try downloading the 7.1 RTE and installing it to see if it will stop. If not, you can try pointing the dialog at the MSI once to see if that will stop it.
Try to take over the world!
