Freedom Force is really annoying to get running on Vista, first of all it wouldn't start. So I installed the latest patch. Now it seemed to work fine, no glitches or anything but when I completed the first level it would not continue. There was no NEXT button and when I try to load the game clicking 'mission briefing' doesn't do anything. I didn't post this in the 3RD REICH forum because it's the original and nobody would have seen it anyway.
Also, you should try uninstalling and installing as Admin. Also set as run as admin through the settings. You would be surprised how many Vista problems that fixes. Vista has a thing about Admin protocols.
