@asiapanda5 Once you've installed the base game, click on the Sims 3 icon in your Origin library. Then click More > Expansion Packs (you might have to scroll down a bit), and you'll see a list of all the EPs; you can download the ones you own by clicking the orange Download button below each one. Repeat for More > Stuff Packs.
