This crack will wean your game from the disk, and after installing it to run the game "Rockstar Games Social Club" is no longer needed, it does not disable Windows Live. Suitable for patch 1.0.2.0.
Installation: drop the files "data.dll" and "LaunchEFLC.exe" into the game directory (Game folder) and confirm the replacement. Also, before installing, I would recommend that you make a backup, that is, save the original files in a separate folder, otherwise you never know, the game will not start after that and you will have to install it again.
