Hi to all!

When trying to setup FileNET IDM Desktop 3.1 (Image Services ONLY) on a Windows NT Service Pack 6 (with all hotfixes), I get the following crash before setup manages to finish (Stage: Registering Components or something):

Application Error

OleMainThreadWndName: 00022100._MP
The instruction at 0x0 referenced memory 0x0.
The memory could not be read.
Click on OK to terminate the application.

The instruction at 0x64d840ec referenced memory 0x052a3ac0.
The memory could not be read.

After a search in Google, I found that probably it has to do with DLL files:

This usually means someone passed bogus pointers to a system DLL, and
the system DLL wasn't smart enough to notice. If you could build
setup with "-g", run it under the debugger, and see where in setup it
dies, that might help.

That client has much software installed including Microsoft .NET Framework and Java Runtime.
So, does anyone know what could be causing this?
