Help. Sims 3 Launcher won't install Store content

@ingeborgslinning  If you're using one of the Alder Lake workarounds to get Sims 3 running, as described here:

https://answers.ea.com/t5/Technical-Issues-PC/Sims-3-won-t-open-Alder-Lake-Intel-12th-gen-CPU/m-p/11057820#M248615

you'd also need to apply it when installing content through the launcher.  The launcher's installer also uses TS3.exe or TS3W.exe and will crash for the same reason the game itself does with no workaround applied.

If that's not the issue, please move the entire Sims 3 folder out of Documents > Electronic Arts and onto your desktop.  If it copies instead of moving, or you get an error when moving it, stop here and let me know.

Otherwise, 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 moved but temporarily not read by the game.)  Don't add any of your previous content to the new folder yet; just download one Store item and see whether it installs, then check whether it loads in-game.  If it doesn't, let me know what you see.

If the one item works, download a few more items and test again, and if everything still works, proceed to install all the Sims3Packs you'd like to use.  Do so a few items at a time, and worlds separately—the launcher doesn't handle large amounts of data very well.

Once you've installed all your launcher-based content, you can move your other content from the old Sims 3 folder to the new one.  Here's a description of everything in that folder so you know what you'd want to preserve:

Thank you so much for the help! 

After downloading the Alder lake workarounds the Laucher starts to install the store content, but after the installation  it says that there is nothing to install. I tried with a few different items and worlds but it just says the same thing. 

I tried to move the sims 3 folder to my desktop but it says that I cant move it as the file is open in another program. 

What do I do next? 

@ingeborgslinning  The "file is open in another program" error is usually caused by OneDrive.  You may want to address that at some point, but the actual error with installing that you're seeing now has a different cause and fix:

For OneDrive, if you want to stop it from syncing your files or get rid of it altogether, please choose whichever option works for you in this guide:

The guide itself was written for Sims 4, but the OneDrive info is universal.
