How to Fix Social Club Error 1014
If when starting GTA V you get an error 1014 from Social Club, uninstall Rockstar Games Launcher and Rockstar Games Social Club.
Remove their files in Program Files and Program Files (x86) folders.
Type Windows + R, and then type regedit.
On the registry search for Rockstar Games, and delete all entries that contains Launcher or Social Club.
That should fix the issue (it did for me).
