Nope it's a fresh Windows 7 install.
I saw from another post that you know to start with a CLEAN install. Other than that, a new download from Matrix with a fresh install should do it. If that doesn't work, like others said in previous posts, its gotta be an antivirus app interfering with the install, or a Directx 9 issue.
Yeah it's a completely new folder I made separately. Does the folder path have anything to do with it?
I use DX11, if that matters.
Don't know if that extra folder is an issue but I wouldn't do that. My version is installed directly on the C Drive, along with Program Files, Documents, etc. DX11 should work fine.
I've got one last idea, rename the Music folder found in the Base folder. Some computers have been known to crash when opening the game because of incompatible audio drivers.
One more thing, next time you try to open the game and it crashes go in the SOWGB/Work folder and find the SOWGB.log file...Attach it here.
