I know that 2002 has problems with 64 bit OS.
How? Because I recently had the same problem with 2002 on XP64 professional.
2002 would work initially but would not open some drawings or insert some blocks that had been done in a 32 bit OS; other drawings opened fine but some it just didn't like.
Then all of a sudden the 2002 stopped working at all; up came the menus and toolbars then wallop- Fatal Error.
Didn't matter if I had double clicked a drawing in windows, opened Acad from the desktop icon, or from the start menu, Fatal Error every time.
Looking it up on the Autodesk website it seems that it is a known problem but because 2002 is out of support and is 8 versions old they are not going to fix it.
PS- I have now junked the 2002 and have 2006 installed on that machine.
Sorry to be negative but I think you may have to go the same route or continue running your 2002 on XP.
