Common Language Runtime Debugging Services Application has generated an exception that could not be handled

Question

Our custom got an error when startup our .NET windows form application.
XXXXX.exe - Common Language Runtime Debugging Services
Application has generated an exception that could not be handled
Process id=0x654(1620), Thread id = 0x5b0 (1456)
Click OK to terminate the application
Click CANCEL to debug the application
If they click on "CANCEL" then following error message appears:
Registered JIT debugger is not available. An attempt to launch a JIT
debugger with the following command resulted in an error code of 0x2(2)
Please check the computer settings
cordbg.exe !a0x654
Click on Retry to have the process wait while attaching a debugger
manually.
Click on Cancel to abort the JIT debug request
We can not duplicate this problem in our development environment and test environment. So, we ask them to uninstall application, .NET Framework 1.1 and resinstall .NET Framework 1.1 and application. They still got same error. We further ask them to install .NET Framework SDK 1.1. They got some detail error message.

Looks like the problem is casued by missing component. But we don't know which component missing and how to find it. Is there anybody can give us some clue what we need to check next and what tool we can use to detect missing component.
Thanks!!!!

Answer 1

I tried Dependency Walker in our development environment, looks like it's useless for .NE T Window Form application, the result I got is like bellow,
XXXXX.EXE
    MSCOREE.DLL
        KERNEL32.DLL
        USER32.DLL
        ADVAPI32.DLL
        SHLWAPI.DLL
        URLMON.DLL
        VERSION.DLL
I know we used some other DLL like Mirosoft Office Object Library, but MSCOREE.DLL (.NET Runtime Engine) covered them. Any other idea? Thanks!!!!
