Re: Sims 4 Execution Error

@1mnz7xa0sy8f  Please uninstall the EA App with Revo Uninstaller (the free version is fine).  Then download a fresh copy of the App installer and run it.  Close the App and restart your computer after it's installed.

Open Steam and the EA App as an admin: right-click the desktop shortcuts and select "Run as administrator."  When they're both open, try again to launch Sims 4.
