This game is not supported on the standalone Paradox launcher, which was only ever meant for non-Steam users anyway.

Having bought a Steam edition you'll have to play it from Steam, I'm afraid!

There is no "Paradox version" I'm afraid; as I said This game is not supported on the standalone Paradox launcher at all.

You can only play the version you have from Steam.
