@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:
https://help.ea.com/en-us/help/faq/clear-cache-to-fix-problems-with-your-games/
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.
