Product Activation
I bought this game retail and can't activate it on steam. Can you only activate Valve games?

Please make some efforts to find RETAIL KEYS ACTIVATION Valve official FAQ. Google is an excellent search engine.

You proaobly can't activate it through steam cause it may not be a steam version of the game. You may have to activate it standalone.
