ok so, i have found my folder, put on it the 2 things and add the patch 2.1.7.5..
but now when i try run teknomw3 it said : " Error during initialization:
Couldn't load fileSysCheck.cfg. Make sure Call of Duty®: Modern Warfare® 3 is run from the correct folder."
i really dont know what is the problem , is it because i have a folder with the patch 2.1.7.5 onto the mw3 folder ? should i put all files in this patch at another place ?
