I found out how you can play a KnP game in Windows 7 (this also works for older OS), you have KnP game files while you have MMF2. You know that MMF2 is backwards compatibility and can import/open Klik n Play files, The Games Factory and Multimedia Fusion 1. Just drag and drop the .gam file on the program and then the program will import it.
It's easy.
I use it everytime because i like viewing game sources.
