AutoCad 2000 has worked on my HP Pavillion laptop/Vista for over a year but recently when the program is opened an error message appears: "AutoCad Error Aborting: FATAL ERROR: Unhandled e06d7363h exception at 7667fbaeh". Then AutoCad will not run.
AutoCad will run with the original program disc in the drive.
I have tried running the Windows compatability program but it makes no difference.
