I have McAfee Viruscan Online installed on my computer and when I click to get virus updates from McAfee, the script "force=OEMID=" and picks up the AutoCAD 2002 installer and tries to reinstall AutoCAD. If you don't cancel it in time, you have to call Autodesk to get a new installation number. This has happened to me once already. Do you know of a patch that can fix this?
