Re: Allied Assault will not launch
If anyone else comes across this problem, I was able to fix this by following a guide from the GOG Version of this game.
The link is Here
Simply download the file and place it in the directory of the game files. You may want to use a fresh install for the game as mine did not work until I did so.
To launch the expansions you have to launch the .exe files manually as there is no way to launch them via the EA Play GUI nor in Game, but at least it works.
There are some graphical issues that I haven't resolved but the game is at least launchable.
