i have the disc physical copy of he game and after installing it multiple times it doesnt launch the game. the map editor works fine with no problem. i tried the compatibility thing with every windows version, deleting the "gamerprofile" xml file, running everything as admin. i tried to verify the files but i always get an error message. "unable to start the game. Please check that your game has been installed correctly. if the problem persists please contact ubisoft support":
