Re: The Sims 3 won't launch, instead opens EA app - Windows 11
@blooobagooo It sounds like you're one of the players who can't use Origin, which is unfortunate since Origin would make troubleshooting easier. Instead, please do a clean uninstall and reinstall of Sims 3:
- Put aside your Sims 3 folder in Documents\Electronic Arts (if you have one) and rename it to something that doesn't include the words "Sims 3."
- Download Revo Uninstaller (the free version is fine) from here.
- Launch Revo, select Sims 3 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.
When you go to reinstall Sims 3, create a new folder on your computer, at the root of the drive of your choice. For example, C:\Games is fine, but not C:\Program Files\Games. Install Sims 3 into that folder; you can just install the base game if you'd like to save time. Then try to play while applying the Task Manager method for fixing the Alder Lake issue.
