"Class not register" when creating in FM client

Hi,
I'm a newbie in FM application. I'm trying to install HFM and i guess it installed successfully without error. But when i'm trying to create a new application via FM client, i always got a msg box error "Class not register". Is there anyone knows this ? Profile was successfully created. Also, in workspace, i can see link Consolidation Administration, but there is no extended link, such as Create Application. Is there something wrong with the FM configuration ? I back and forth configure the HFM and workspace for a couple of times, and not to mention uninstall and re-install it again. but still couldn't find why. Please help. Thanks.

Hi again,
I tried to re-install the FM Application Server. Then I re-configure FM and workspace, and try to create an application through FM Client. This time, the error given was "You do not have the proper access rights to perform this task". I've checked in Shared Service and the login that I'm using now is perfectly provisioned with Administrator, Application Creator and Dimension Creator. I even tried to deprovisioned with Application Creator and provisioned again with Application Creator. I still got the same message error.
In fact, I re-installed FM (except the EPM), configuring and still got the same error. Is there anything I set wrongly? Please help. Thanks.

Class Not Registered error when opening COM+ Applications folder

Hi,
This question was originally posted in the Microsoft Community / Win 7 forum, but I was asked to post it here.
As you can see below, I'm getting Error Code 80040154 - Class Not Registered when clicking on COM+ in Component services.
...picture 1 coming / Account verification
I took a look at the event logs but couldn't glean much information from them.
I also have issues associated with MSInstallVSSProvider when Uninstalling / Installing Norton Ghost 15. Not sure if they are related or not.
Below are the errors I get when Installing Norton Ghost 15. This app had been loaded on the PC earlier with no problems whatsoever. A few months later when launching the app, I got several error messages. Couldn't resolve them so I thought I would uninstall
/ reinstall. That's when I started seeing the MSInstall errors, which lead me to the Component Services area.

I suspect a registry cleaner (GlarySoft) is the culprit here. My mistake was not backing up the registry before running the scan. This won't happen again.
Thanks,

Hi,
In the event error, can you read what {GUID} encounters the error message? Please also let us know the full error message.
Based on my search, this issue can be caused by the incorrect registry permission settings.
Please launch Registry Editor and navigate to HKEY_CLASSES_ROOT\CLSID\{GUID} to verify the permission settings.
If it does not work, you may run Process Monitor to check what process encounters this error.

Class Not Registering

I have not programming in a few years and found when I
started using my Homesite Ver 5 that I could not create a new
Project - got Class Not Registering when attempted to enter. I did
a plain uninstall/reinstall without benefit. I then searched the
site I found a reference to an elaborate reinstallation Knowledge
Base Article indicating that I should uninstall, clean out all
files in the Homesite5 directory, remove a couple of registry keys
(which were not there) remove two InstallShield Installation
Information files (which were not there) and then move the Install
Shield Engine and Scrip to the desktop and install from a copy of
the Installer Exe copied to the desktop from my CD. I did not do
the latter and the problem remains.
Now that Knowledge base article does not specifically refer
to my situation although one user claimed that solved his problem.
Surely there is a better way. I installed this program at least
three times when I lost a HD and bought a new computer. It has
always worked. I am stubborn but just what file is not registering
- I'll reregister.
Appreciate any help to avoid moving Program files to my
desktop and installing from my desktop - anybody know why it will
not longer works?
Ed

Thanks Roy - that was what I needed. Embarrassed that I did
not find since I thought I diligently searched for class not
registered - and of course did pick up the "wrong" one. Hard to
understand why that ever worked with a folder name essentially mal
formed. Once working deleted the old bin and having trouble getting
rid of the Micromedia with Windows telling me that it still
contains something (that I can't see). Will try booting to DOS.

Class not registered error, when open HTML files.

Hi guys, recently I've been facing this problem, everytime that I try to open a HTML file it shows the error message "class not registered", I've tried reinstalling and yet no luck, this only happens with firefox because I also have IE 10 and it works with that one but you know, I love firefox so I want to open them with it.
Additional Info:
I'm using firefox 20.0.1 on Windows 8

Try to redo the default browser setting and temporarily set another browser like IE as the default browser.

Class not registered TSLV when attempting to run a report in CE10 w/ sp2

I'm running Crystal Enterprise 10 with SP2 and receive the error message when I attempt to either schedule or run to screen any report.

there was a conflict between the local Crystal Reports and Crystal Server client tool components. I had to uninstall and reinstall both solutions and was required to install and Crystal Reports related software and service packs first. Then the Crystal Server components installed with no issues.

"Class not registered" Error when running Windows Explorer

Hi,
I've been having trouble running Windows Explorer + any related programs (Control Panel, Internet Explorer, etc.). Whenever I try to run such programs, a popup containing the following comes up:
C:\Users\<username>\AppData\Roaming\Microsoft\Windows\Start Menu
Class not registered
Any help? I've tried using a registry cleaner, and the command regsvr32 ExplorerFrame.dll didn't work. I don't recall installing anything, and everything else seems to be fine.
Thanks in advance.
EDIT: I've tried System Restore, didn't work.

Excel Viewer: Class not registered (error -2147221164)

Hello,
I am using the Excel examples shipped with Labview 8.21 to read from an Excel file and this works well. Now I need to do the same but on a PC that does not have Microsoft Office or Excel installed but only the free XLVIEWER (Microsoft Office Excel Viewer). When I try to change the ActiveX class of my reference to feed the 'Automation Open' vi I get the Class not registered (error -2147221164) although I can browse down to the XLVIEWER.exe and select it. Then I thought that maybe XLVIEWER had no ActiveX to communicate with other application; I thus installed a package called excelocx.exe, rebooted the PC but that did not change anything. I am still stuck with the same error.
What am I doing wrong?
Thanks a lot,
Christophe

Please find attached the VI I am using together with the XLS file that I try to read with Labview on a Pc that does not have MS Excel installed, only the XLVIEWER.
OpenOffice is not supported in our company so cannot be considered as a valid solution.
Thanks,
Christophe

I Get an error every time I try to update Windows 8.1 or update Defender (EXE On top "Class not Registered")

I think my lap top has a lot more problems, then the sun has Hot spots! :)
(not that I am down playing any one's situation, nor want to sound cynical or Condescending).
Though many of my issues have been resolved through a LOT of time, tech support and a couple friends and personal researching.
But I get the "Class not Registered" Every time I try to update Windows,
(I have Mozilla Firefox 30 and Windows 8.1)
On Top of small Error box, I get EXE..on top. But Inside the error box "Class not Registered"
Some of the other issues or problems were self inflicted by not researching properly, so to say the least I am being extremely cautious.
I have the same issue with Class not Registered, and looking for some ideas or hopefully the solution.
After I try running a windows update and any updates for my virus scan "Defender" which is what I believe windows 8 and 8.1 uses, I am not sure about Vista or Windows 7 have, I never used them.
I went right to 8 through a new lap top. Then I got Windows 8.1 (that was about a month ago)
But if anyone does find or even know an answer please reply as soon as you are able, anyone else who may just be reading, if someone gets anything that did work for them, Please Let me know.
Due to time I couldn't read through more Forum suggestions or links that may work for
My Error EXE. "Class Not Registered" :)
BUT will return later in day. Maybe anything I found an answer for I can pass on. i Have had plenty issues since I had a type of crash (Or whatever it was when I was online with a Tech from Microsoft and and he had it so both of us could control the Arrow cursor, I double checked phone number for MS and it checked out legit,
That was the beginning of many days of constant repairing That was back around July 6th 2014 Thanks to everyone who even just reads this, BuddyD

This is might because of your prior change in softwares. so first you have to do run '''sfc''' in run command. and then you see the specific problem which causes this . Since System File Checker (sfc) scan will make Windows replace corrupt or missing system files on your computer.
* Click Start>All Programs>Accessories>right-click Command Prompt, and select Run as Administrator.
* Click Continue or supply Administrator credentials if prompted.
* In the Command Prompt window type the following, and press Enter:
sfc /scannow

Class not registered

HD-4310 Webcam software.
When installing I get this error message:
" Class not registered " (without speech marks)
I followed a tip to use " sfc /VERIFYONLY " to scan for a permissions problem but my system comes up clean.
Can anyone help?
Much appreciated

Thanks for the expansive reply. I must say, I disagree with your statement: “As I said, it was a problem with the HP Webcam installation, not Windows Explorer. It's a good job I didn't take your suggestion for a solution in the first link and act on it.” I am going to provide an elaborate explanation as to why I disagree with this statement.
Firstly, I'm going to provide you with the most significant troubleshooting steps from the first link I provided (link is http://answers.microsoft.com/en-us/windows/forum/windows_vista-desktop/explorerexe-class-not-registe...
“Hello,
I would suggest the following support steps....
-Load into Safemode and verify if you are able to access your desktop
-Create an alternate user account and verify if you are experiencing this issue.
-System Restore your computer to a previosu date and time when it was functioning normally.
-SFC /scannow
-Perform a repair Installation of Windows. (Universal steps are listed below)
Please proceed with performing a repair installation of the OS. In case of a failure, please ensure that you back up your data to an external location prior to performing the repair. Below are the steps to proceed with the repair process.”
I will cut the quote at this point. Now, I have worked, researched, and experimented with software on Windows since 2000. Running the computer in Safe Mode is always a troubleshooting step. The part about accessing the desktop may not apply, however, running in Safe Mode is crucial and helpful. I cannot describe how vital it is in certain types of troubleshooting. Creating a new user account and attempting to perform the same mission can potentially repair all “Class not register” errors, not just specific errors. Of course, this will point to an issue on your primary account. The system file checker scan is always valid, because you never know what it will detect, which can be significant. A System Restore may or may not work, depending if the software did work at a certain point. Finally, a repair installation of Windows, while it is a monumental task, is a troubleshooting step.
Secondly, I noticed the Operating System that is subjected on the thread is Windows Vista. I informed you that I would require you to inform me of your operating system, and model number, so I can assist you further. However, the funny factor about the more recent Windows operating systems is that troubleshooting is extremely similar on all operating systems. I provided the best thread I could, without knowledge of your operating system, since the troubleshooting provided applied to Windows 7 as well.
Thirdly, I'm going to quote your statement, then provide my response:
“The better advice would have been to let me know how to find the Problems and Solutions in the Action Centre and get some more information before a complete repair of my entire OS. I can't remember how I found out now, but I couldn't find them there and took a tip to type the name "problem reports" into the search bar of the start menu and click on "view all problem reports”.”
While this troubleshooting is valid, my style of troubleshooting enables this troubleshooting step to only be performed on special occasions. This issue was not one where I would've elected to perform this task. My troubleshooting I provided would've narrowed down the issue, ultimately, if it wasn't resolved. Even if I had to troubleshoot this issue from scratch, I would not perform this task.
