Re: Sims 3 expansion pack not downloading from EA app
I've had this problem trying to install Sims 3 from the new EA desktop app. The base game and every expansion besides Into the Future, Island Paradise, and I think University (there was 1 more) kept getting stuck on preparing. The Origin fix worked for me.
1) I downloaded Origin from https://www.dm.origin.com/download
2) I let everything that installed on the EA desktop app install there.
3) When I reached the expansions that were stuck on preparing, I closed the EA desktop app. Don't cancel the installs.
4) I installed and opened Origin and signed in. There's a big popup to download the EA desktop app, but if you leave it open you'll see all the installed games verifying then start downloading the ones stuck on preparing:
5) After they install with Origin you can close Origin and open back up the EA desktop app. The expansions were still stuck on preparing for me on the EA desktop app, but I cancelled them and they still showed up fine in the Sims 3 launcher. All should be good after that.
