I have been trying to run AutoCAD 2006 on a friends Windows Vista Home Basic for the past few days. Basically, it installs quite alright but when I try running it, it keeps showing me this message about compatibility issue. I have decided to run an update on this vista home basic and I hope this will solve the problem. But before I get any further I would like for anyone to help me on this as I wait for the result on the update. Thanks
