If you are encountering GameGuard error 111, it is more than likely that the GameGuard folder was not created correctly during the initialization phase. This can happen when the GameGaurd installation is blocked do to incorrectly set administrator permissions.
To resolve this issue please try and run the game client and NClauncher2 as an administrator. To do this, right click either your Lineage 2 short cut or your NC Launcher 2 short cut and click "Run as Administrator"
