Went to load game last night (wed) and a CMD prompt opened saying that DayZ_BE.exe failed to run, then it said it was installing and finally said it failed to install. I had just turned PC on, it worked fine the night before. After rebooting everything was fine. Battle Eye installed and game ran all night. Not sure since it was Wed if there was just a Battle Eye update that was having trouble or what but after rebooting the problem corrected it's self.
