Pc Had Origin Installed, and Has new Ea Launcher - TS3 Won't Launch

@GreenPiratez  Rather than usint the .NET Framework repair tool, it's more effective to uninstall and reinstall the framework entirely.  First though, 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, hit Windows key-R, enter "appwiz.cpl" without quotes, click "Turn Windows features on or off," and you'll see .NET 3.5 near the top of the list.  Click the filled-in box to uninstall, then restart your computer.  Repeat the process, except now you'll click the empty box to reinstall, and restart again.

Please repair Sims 3 itself in the EA App before trying to play, and instead of using the Alder Lake patch or the PowerShell method, please try the Task Manager method.  It's the most inconvenient fix for the Alder Lake issue but also the most reliable.
