sims 4 problem

@Daty456  When you have Sims 4 installed through Steam, it can only be repaired through Steam, not through the EA App.  To do that, open your Steam library, right-click the Sims 4 tile, and select Properties > Local files > Verify integrity of the game files.

Please also go into Documents > Electronic Arts and move the Sims 4 folder to the desktop, then try to play.  Let me know whether you can start a new save and play in live mode.  If you can't, please describe what happens when you try, including a screenshot or the exact text of any error code you see.  The important thing is how the game runs, or fails to run, right now.
