PartyCAD 12 works fine on Windows 10, 8.1, 8, 7, Vista and XP.
Versions earlier than PartyCAD 12, like PartyCAD 9, 10 or 11 for instance, will not work well on Windows 10.
PartyCAD 12 will not run on Windows RT machines like the original Microsoft Surface, but will run on the Surface Pro or any machine that can run desktop apps. The key thing to look for when buying a system for use with PartyCAD 12 is that it does not have the RT version of the Windows operating system. (More about RT here.)
