Duplicate Product Key

A retail Product Key may only be registered to one Steam Account. Product Keys are authenticated to your Steam Account, not the computer on which the game is installed.

As long as you have access to the account on which the game is registered, the game will be available for you to download, install, and play in your Library list regardless of the computer you are logged in on.

If you have lost access to your Steam account or you are certain you have not registered your Product Key to a Steam account in the past please contact Steam Support.
