The Sims 3 launcher has stopped working.

Andre001507​  Please clear Edge's Internet Explorer-mode data, as described towards the end of this article:

If that doesn't help, let me know whether you've recently upgraded to Windows 11, or installed it fresh—I've seen a few comments about Windows 11 breaking the launcher.  And if the launcher works but the game itself does not, please describe what happens when you try to play.

Hello, first of all, thanks for the reply. So, I still have Windows 10, and The Sims 3 has always worked fine for me so far. I followed your advice and deleted the Microsoft Edge browser. The launcher now starts normally again, and I can click the arrow button, but the game doesn't start. I just get a black screen, and the loading cursor spins for minutes without the game starting.

Andre001507​  I apologize for the late reply.  Please move the entire Sims 3 folder out of Documents > Electronic Arts and onto your desktop.  When you open the launcher, a clean folder will spawn with no content.  (Your saves and other content will be intact in the folder you've moved but temporarily unread by the game.)  Don't add anything to the new folder yet; just start a new save and see how it runs, that is if you can get that far.

If that doesn't help, please provide a dxdiag.  Click Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop.  From there, you can attach it to a reply using the paper clip (Attachment) icon included with the other formatting buttons.

Okay, the game is running again. I still don't understand what the actual problem was, but the game is working again. Can I add my mods folder back now?

Thanks for your help. This post can now be closed.
