The Sims 3 Launcher Won't Launch

Nursey318  What happens when you try to install your Store content?  If you get an error, please provide a screenshot.  And let me know whether the launcher is still blank after clearing Edge's IE-mode data.

If clearing IE-mode data doesn't help, is this an original Windows 11 install, or did you upgrade from Windows 10?  Did the launcher ever work on this computer?

I did that & it didn't work for me. Still won't open!

praisethebastii  What exactly did you try, and what happens when you try to play?  Please post a screenshot of the error, if you get one, or write out its text.  And let me know whether the launcher opens at all, and if so, what it looks like.

I'm having this issue I’m going to give it a go 

JohnTrainor11​  Let me know how it works out, and if you still can't play, please post a dxdiag as described in my first reply in this thread.

Hello! I am having similar issues with a resent update to Windows 11 and EA app. My launcher works, but my purchased Sims 3 store content will not appear in-game. I was able to fix my blank launcher screen by resetting my password with EA. Now I can download Store items into my launcher, install, and they appear in the "Installed Content" tab of the launcher. However, when I run the game, no Store content is there. All my Expansion Packs and Stuff packs are present however. In my troubleshooting, I did uninstall/reinstall the game, and the game files are in Disc C/Program(86x)/Electronic Arts/The Sims 3 2025. My "installed" store content is not downloading here. It is downloading to Disc C/Users/Noelle/Documents/Electronic Arts/The Sims 3/Downloads. This is an old file with my saved games etc. The new reinstalled 2025 file for the game does not have any "Downloads" folder in it. Thoughts?

Also when I play the game, and exit again, the content now shows as "not installed" in the game but is still in the downloads section of the launcher.

noelletastic321​  Sims 3 always has two folders, the program files (what you installed through the EA App) and the user folder (in Documents > Electronic Arts > The Sims 4).  Your Store content is downloaded into the user folder, where the launcher can read and install it.

It sounds like you need to install the Store content into a clean folder though.  Here's how:

puzzlezaddict​ THANK YOU! The link you shared helped me fix it! I renamed my Sims 3 folder so it would spawn a new one and that seems to have fixed everything! Now I can work on re-downloading store content and moving saved folders. THANK YOU <3
This game is truly one of a kind, it's infinitely better than any other Sims game, and I don't know what I will do when it stops working with modern machines. Thank you thank you thank you <3
