If you try to install BF3, it will ask you to install Origin first. Then eventually it connect to internet to download 11GB BF3 files. I know it’s a bit frustration when you have slow internet connection that takes you about 6-12 hours. No worries!
Here are the solution :
1) Download the latest Origin (http://www.origin.com/download) **If you have already installed the Origin from the disc, please uninstall it and download the latest version.
2) Autorun from disc
3) Login and redeem the code
4) Wait for a moment and notice the speed will up to 4MB.
6) Enjoy your game!
