Installation: Spoiler 1) Find your Rockstar Games folder (in your Documents)
2) Open the Rockstar Games folder, then GTA V, then Profiles, then 774C1548 (Yours may be different but it should be the only one in your Profiles folder)
3) Copy and paste SGTA50001 and SGTA50001.bak (you may have to rename these if you already have files with the same name) into the 774C1548 folder
