I still haven't gotten this to work either. I originally had this running on this machine with this video driver and the same printer driver. It worked fine. I think that my W2000 had a service pack 1.
I then had to give the machine to the system administrators to rebuild to a corporate standard configuration. They repartitioned the disk, and reinstalled W2000, 5.00.2195 Service Pack 3. It hasn't worked since. This is an HP 6100, 1.12 Ghz, 1 Gbyte RAM, ATI Mobile Radeon (16 MB).
We sent a Compac laptop to get reconfigured by the same group, supposedly to the same spec, and Minicad worked fine on it when it was returned. It does seem associated with this laptop somehow, although it used to run on this laptop for nearly a year.
I have tried to update the video driver, and the printer driver, and chosen a different printer, but nothing works.
