The developers of this game have decided to no longer support the game on the standalone Paradox Launcher, so no new patches or DLCs are available there.

You'll need to play it from your Steam library from now on.

Sorry about that!

You don't need to. Just instal it from Steam and the latest update will be there automatically.

Not sure where you are stuck exactly.

When you bought the game from us (Jul 9, 2019) we sent you a Steam Activation code by email, and it may also be visible here:

Paradox Accounts

accounts.paradoxplaza.com accounts.paradoxplaza.com Click on Manage for the relevant game, the key should be visible in there.

THEN You must have, or create, a Steam account and install the Steam Client application from their website.


Steam, The Ultimate Online Game Platform

Steam is the ultimate destination for playing, discussing, and creating games. store.steampowered.com store.steampowered.com "Install Steam Now"

Just paste your Steam Activation code 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

Does that help?

You have to reinstall it, as the Steam edition is different from the standalone Paradox launcher edition.

You can leave the standalone one or remove it, it makes no difference to the Steam edition.
