I just found this Website/Forum and also have this problem. I use Windows 7 in Virtual Pinball Cabinets and would like to create a slipstream copy of Ultimate 7 for offline install on these. Does the v1.7.0.0 also work on Windows 7? I just Dl'ed it but can't find anywhere that says it does, and now I found this thread so I assume I need an older version of the Toolkit?
