Before you install it make sure that you meet these criteria:
- Make sure you have a clean install of 7.62 High Caliber(if you have vista/Win7 don't install it in the Program files folder, that might cause writing violations)
- Extract the Unofficial Patch files to your game directory
- Run the PatchMe.bat to pack up the files in an AZP archive
- Remember to run PatchMe.bat as an Administrator
2: This should be fixed after you've patched the game.
