Unfortunately, each program start ends with the nagging indication that a driver is not installed correctly, and you end up back on the desktop. The game therefore does not play itself. Is not changed by a new download in addition to reinstall anything. My fully patched Windows 7 (64-bit), however, complained since the first installation that at once a driver is installed, which would be blocked due to compatibility issues, as it will affect the system stability. This is to the Ubisoft for Rainbow Six: Vegas used "day" copy protection. The statement from Amazon, it would not install any additional software, so is wrong. Actually this installation even borders on criminal damage. I can not remove from my system this copy protection driver namely. Even after complete uninstallation of the game this driver is maintained, although it is useless and would be used only by this Ubisoft game. The Money Pit this. My advice: Stay away!
