What Fixed the Issues for me! (Windows 7)
I'd tried every suggestion within these forums to make Freedom Force run normally. Like many others, as soon as the first mission launched, I couldn't make Minuteman go anywhere that I wanted to. Sometimes he wouldn't move at all, other times he'd run in crazy circles or off the map.
I tried running in every compatibility mode I could find, and always ran the launcher as Administrator. Nothing worked.
Finally, tonight in frustration, I launched the FForce.exe OUTSIDE of Steam. That's it. That's all I needed to do. I have no idea why this should make any kind of difference at all, but it did.
If you've installed the game to the default directory, it should be located at:
C:\Program Files (x86)\Steam\SteamApps\common\Freedom Force\fforce.exe
If you don't want to manually create a shortcut to your desktop, right-clicking on the app in your library and creating a shortcut from there, and then launching from that shortcut also seems to work.
The only time it doesn't work is when I launch the game from inside the steam interface.
Don't know if this'll work for anybody else, but it did for me. Hope it helps!
