Re: How to play The Sims 3 through Origin

Did you register your game on the Sims 3 website? If not, read here how to do that:

After you have registered your game and the EPs and SPs you have there, please download and install the Origin client from here:

www.origin.com/download

Log into the Origin client with the same account (= email and password) that you used for the Sims 3 website. The game, expansions, and stuff packs will show up there like this:

Now you just double-click on your game and it starts to download and install. After you have installed your game, you can start downloading and installing your EPs and SPs.
