TS4 is not launching - Help

slavichorsegirl​  For running Steam and the EA App as an admin, I didn't mean that you needed to set them to run with admin rights in general.  I only meant that you should manually run them as an admin one time, as a test, by right-clicking and choosing the option directly in that right-click list.  You can remove the "run as admin" setting under Properties for both apps.

Your dxdiag shows some Windows processes are crashing, so 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.

Next, please install the newest graphics driver Nvidia provides:

https://www.nvidia.com/en-us/drivers/details/245376/

Run the installer as an admin (again, right-click, Run as administrator; no need to dive into Properties).  Choose the Custom install method, not Express, and check the box to perform a clean install.  When you see the list of features you're installing, make sure the sound driver is selected.  Restart your computer after installing and before trying to play.

If you still can't open the game, please try with Norton disabled, temporarily of course.  After disabling Norton, repair the game in Steam (Sims 4 > Properties > Installed Files > Verify integrity of the game files) before trying to play.  As long as you don't do anything else while testing, your computer should be safe.  If this helps, you can set exceptions in Norton for TS4_x64, TS4_DX9_x64, and TS4_Launcher_x64, or the entire Bin folder they're in.  Set an exception for EADesktop.exe as well.
