Sniper Ghost Warrior 2 CD Key

[Short Buss]

Bought this game today, tried to install it and has a pop up screen asking for a CD Key. The game does not have a CD Key. Purchased brand new at Walmart. Took that one back to exchange for a different copy and same thing, no CD Key. Please help.

I bought this game, thinking I had no key. But mine was on the hard plastic case on the back. Take the tape off the first case (which is most likely just a sort of paper case) and then flip the plastic case over and it should say "ACTIVATION CODE:"
