I have the same problem, have you found any solutions. ?
Thanks for any help
I had the same problem in Vista as well as Windows 7, runs for a while the when I start it up it crashes and won't even open.
What I've found to make it run & open ,(And it makes no sense to me) is to put my thumb drive in and then it will let me open the program. If I take the thumb drive out and try try to open Acad 2002 it immediately crashes worked this way in Vista as well.
Very Strange, however after a while in Vista the thumb drive solution stopped working, maybe it will happen in Windows 7 too.
64 bit to 32 bit must lie at the heart of the problem.
Hope this helps.
Install XP mode & Virtual PC and Autocad 2002 will work fine, I had problems for a long time with Vista and Windows 7 , Installed it and it works great.Cool Beans !!
