Patch Installation Problems
I am having trouble installing a patch, either through the auto-patcher or manually from the patch site. The error I get is The game is not installed on your computer. How can I resolve this?
If you have the Ghost Recon Advanced Warfighter 2 demo installed, you may have difficulties trying to patch the full version of the game. Please be sure to uninstall the demo(s) BEFORE you install the full retail game to avoid conflicts.
