I upgraded one of our notebooks to Windows XP professional and then tried to reinstall IronCAD. The installation passed the operating system check, but failed with a number of 1645 (and nothing else) being displayed in the install shield wizard. The pre-req's published indicate support for 2000, NT 4.0, or higher. We have successfully installed on 2000 pro and NT workstation.
Do we need an updated installation package?
