I have an old Parsons Technology CD for The Kingdom of the Cults, dating from the mid-90's that was designed for Windows 3.1. It runs on some XP machines, but not well. Is there a later version designed for XP or Windows 7?
I am afraid that the product will not work in Windows 7 due to its compatibility and design issues. It's a program created for Windows 3.1 which is practically the 3 or 4 version of Windows and it was released more than 20 years ago. But if you say that the product works in XP then you can use the Windows XP mode in Windows 7 and your product will work but with limitations, as you said.
