Hi, I am trying to update Halo: combat evolved, but whenever it trys to update it will download the update then execute it then it wil ask for admin rights. Well I have admin rights and I even tell it to run with admin rights. I also have UAC disabled, and yet I cannot update the game. Has anyone else out there been able to succesfully update?
