If you bought these DLCs from the Paradox store, as is likely, they will not automatically appear in Steam. You need to redeem the Steam Keys we sent you into your Steam account for them to be there.

Just paste your Steam Activation code AAAAA-BBBBB-CCCCC (which we sent to your email, and is in your Paradox Games menu) into the +Add a Game area of the Steam client application, and the game will be available in your Steam Library in that Client to download and install. You can also do this directly on the Steam website
