The sims 4 not launcing in EA app

@elisepaas  Thanks for the dxdiag, which shows a few failed Windows updates that should be addressed.  I doubt they're interfering with Sims 4, but it's usually easy enough to fix.  Please start with 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.

For the error itself, do you use a third-party antivirus?  If so, please disable it, clear the EA App's cache:

and repair the game again.  Don't reenable the antivirus until you've tried to launch Sims 4 again.  As long as you don't do anything else at the same time, your computer should be safe.  If this helps, set exceptions in the antivirus for TS4_x64.exe and EADesktop.exe.

If this doesn't help, have you tried moving the Sims 4 folder out of Documents > Electronic Arts yet?  Please do so or let me know that it didn't work.

The next step would be a clean uninstall and reinstall of Sims 4:

• Put aside your Sims 4 folder in Documents\Electronic Arts and rename it to something that doesn't include the words "Sims 4."
• Download Revo Uninstaller (the free version is fine) from here.
• Launch Revo, select Sims 4 from the list, and click Uninstall.
• Once the game is uninstalled, select "Moderate" under "scanning modes," and click Scan.
• Review the list, in case there's something you want to save; otherwise, click Select All, and then Delete.
• Close Revo, and restart your computer.

Uninstall the EA App with Revo as well.  I don't have instructions for that at the moment, but the process should be straightforward.  Restart again when you're done.

Install the EA App, then create a new folder into which you'll install Sims 4.  The folder should be on the root level of the drive of your choice, for example C:\Games is fine, but not C:\Program Files\Games.
