How do you download a game off of eastore.com

After you buy the game, you'll be instructed to download EA Download Manager which you can get from ea.com/eadm. You'll download and install the application, and once you login (using the same email address you used to buy the game), you should see your game. When you see the game, double click on it to start the installation process. You'll confirm that you want to download it, accept the game's end user license agreement, and EA Download Manager will install it for you.

A few games you purchase from eastore.com aren't downloaded with EADM. The store gives you separate instructions for these games.
