Sims 4 won't launch in the EA app 20/01/2024

@SkyeB666  What exactly happens when you try to launch the game?  Does it not open at all, does it throw an error, etc.?

For troubleshooting, try pausing OneDrive syncing; right-click the cloud icon in the lower-right corner of the screen to see the option.

If that doesn't help, try forcing the game to launch in windowed mode.  Go into Documents > Electronic Arts > The Sims 3, open Options.ini, search for fullscreen , and set it to 0 (zero).

If that doesn't help either, please look for new errors in the Reliability Monitor.  Hit Windows key-R and enter "perfmon /rel" without quotes, and you'll see a chart of errors and updates with a column for each day.  Today is on the right.

Look for an error that happened at exactly the time of your most recent attempt to launch Sims 34 specifically after you've done the steps I listed.  If you find one, double-click it to see more details, then copy that info and paste it into a reply here.  If you don't see a new error, check back in an hour or so—the Reliability Monitor doesn't always update right away.

Here's the information I found when I used "perfmon /rel" -

@emma_g345  Is this before or after uninstalling and reinstalling the EA App?  And did you use Revo or do a normal uninstall?  The normal way isn't nearly as thorough.  I ask because that would be the first suggestion if I saw this error.  So please do uninstall specifically with Revo if you haven't already.

If this is happening after you uninstalled the App with Revo, please run a couple of basic checks of your Windows system files:

• Hit Windows key-X
• Choose either “PowerShell (Administrator)” or “Windows Terminal (Administrator),” whichever option is offered
• Inside the window that appears, copy and paste “DISM.exe /Online /Cleanup-image /Restorehealth” without quotes, and enter
• The system will start validating soon. If it throws an error, please list it here
• After it reaches 100%, hit Windows key-X again
• Again, choose “PowerShell (Administrator)” or “Windows Terminal (Administrator)”
• Inside the window, copy and paste “sfc /scannow” without quotes, and enter
• Post the message you receive here

Restart your computer, hit Windows key-i, select Update & Security, and click the box to check for updates.  If any install, restart again afterwards.

Run the EA App as an admin: right-click the desktop shortcut and select "Run as administrator."
