I have tried everything I can think of. Re installation of both the game and uPlay multiple times. Cleaned the registry. Uninstalled all other Ubisoft games. I've tried all the possible solutions given from the Farcry 3 or Assassins Creed 3 boards.. The game simply refuses to launch. It has not opened uPlay even one time.
This is the error is displays:
There was a problem starting your game. Make sure you have no other games running that use the Ubisoft Game Launcher. If the problem persists, try reinstalling the game.
(Note: Steam preorder purchase.)
