I just purchased The Sims 3 Island Paradise with the current deal. I was able to download it to "My Games." Now I have to install it and the installer is prompting me for a registration code. There are no codes, except for the bonus registration packs, on the recipt within origin and I have not recived any emails. It is not in any of my spam folders.
If the game was purchased recently, try reloading your games library via the main menu (2nd entry: Reload my games) or click the refresh icon in the top left of your games library. Origin requires a restart or refresh of your games library before if will show product codes on the game details page after a purchase.
Hope that works for you. If not, please contact a Game Advisor at https://help.ea.com/contact-us and they will be able to provide you with your code.
