Okay that sounds like an registry issue but as you tried to clean the registry already we need to dig a little bit deeper in to the problem. Could you provide us some more information about your hardware? You should try to run the installer in the windows XP comparability mode, sometimes installer from older games have issues especially with 64bit clients. You can activate your game via Origin and download the gameclient there. Download and install the latest version of Origin at www.origin.com/download (and make sure you have your Origin account ready as well). Sometimes older games can cause trouble with code redemption directly with the Origin client. To redeem your code with Origin, please try to activate your codes on following activation website instead of using the Origin client for redemption.
Please keep us updated!
