Re: It Takes Two will not launch (STEAM Version)

My boyfriend is trying to play it takes two with me and he downloaded the friend pass version since i own the game. Everytime he tries to launch it the message "It's already started, it's a good one" but he cant find it open anywhere even on task manager. He has already tried; 

- uninstalling and re-installing the ea app

- clearing the cache

- reparing the game files

- deleting specific app data files

- restarting his pc in a clean boot

- force closing the app

- reparing his pc for corrupted files

- installing up to date drivers and GPU's
