I have downloaded this from Skidrow's Site and can confirm it is working perfectly on Windows 7 x64
You need to have a clonedvd version of the game and have it extracted using the latest Phoenix. Make sure you update and download cdr in phoenix before you scan the .sim file located in the FEAR 3 iso. Then extract.
Once extracted copy over files in crack folder to the root folder of FEAR 3 that you just extracted using phoenix.
