Game not running

Do you see the Paradox Launcher after pressing Play in Steam?

Please try a clean install the launcher following the steps in this post.

If that doesn't help and you're still not seeing the launcher, or if you already tried that, please let me know.

Did a clean install of the launcher following the steps linked to above help at all? Or does the launcher still not appear for you?
