File version 10002:40000 (for C:\Program Files\Rockstar Games\Social Club\socialclub.dll) File version 10000:5d50000 (for C:\Program Files (x86)\Steam\steamapps\common\Grand Theft Auto V\GTA5.exe) The launcher.txt file from User>Documents>Rockstar Games>GTA V told me the following:
The launcher starts then immediately stops and says GTA V exited unexpectadly, as if it didn't even try to do anything. When the game attempts to launch via the social club launcher, it just gives up.
