[Kerbal Space Program] I bought the game on the KSP Store, but I want it on Steam. Will you give me a Steam Key?

We are no longer able to transfer Private Division Store licenses to Steam for those who bought KSP before it originally came out on Steam, March 20, 2013. 

 

You can add Non-Steam games to Steam by clicking the "Add a Game" button in the Steam client and then "Add a Non-Steam Game".
