Unexpected Error when running Program on Windows 98

I have a program written in Visual Basic 6 that has been in existence for a decade that runs on all Windows operating systems from Windows 98 and above.  

I still have a client running Windows 98 because they are running an old analytical instrument and can't upgrade the Operating System in fear that their analytical instrument will no longer work.  

I can install my program on other Windows 98 systems and it works fine but with one PC I get a "Unexpected Error" as soon as I attempt to run my program.  Does anyone know what this may be?

It's probably missing one of the runtime libraries required for your program.

I would go with Dave's comment.
-You might also check if it the machine is as up to date as the other workstations.
-Or check Add/Remove Programs / Windows Components to see if people didn't turn off a feature you're program relies on.

Dave and Vinden,

I downloaded the Visual Basic Runtime Libraries from Microsoft "vbrun60sp6.exe" and installed it on the Windows 98 machines that are getting the Unexpected Error but I still get the same error.  I also checked the other Windows 98 workstations that are working and check the to see if anything was off in the Add/Remove Programs/Windows Components.  Do you have another recommendation?

Thanks!

I'd be looking for dll's that were used.  I don't know if "vbrun60sp6.exe" would include everything you needed.

Commented:
Care to share the program code ?
Or tell waht it is supposed to do, so we can determin what it might rely on ?

Dave and Vinden,

Sorry for not getting back to you sooner.  I determined that all dll's are present.  I'm starting to think I should reinstall Windows 98.  Any other thoughts would be appreciated.

Vinden,

I can send the Setup.lst file to you that shows the dlls that are installed.  Describing the program would be quite wordy because it does quite a bit.  Is there something I should focus on in the description?  The Program Code is way too large 200,000+ lines of code.

Thanks,
