I installed the wireless driver for xbox 360 controller http://www.microsoft.com/hardware/en-us/d/xbox-360-wireless-controller-for-windows then i decided to go buy a wired controller since mine was old and dirty. so when i tried to install the driver for the wired controller it said i already had it installed so found the file in program files and deleted it there and deleted the short cuts. Now when i try to install the correct wired driver it doesn't install and says i already have it installed and need to uninstall it. Any ideas on how to remove the remaining files?
