Re: Sims 4 app won't open it just opens EA

@juvancic  The idea is to move the Sims 4 folder in Documents > Electronic Arts to the desktop, not the Sims 4 folder that contains the game's program files.  However, if you've installed the game itself into Documents > Electronic Arts, that would explain why Sims 4 appears to not be installed once you've moved that folder, and it also may explain the underlying issue.

To check, please open the EA App game library, click Sims 4, and select Manage > View properties.  You'll see the install location there:

If it's anywhere in Documents, please list the full file path, and don't do anything else.

Otherwise, move the Sims 4 folder that's in Documents > Electronic Arts and see whether you can play.  If not, please run a dxdiag and attach it to a post.
