[2022] Unable to install Royal Court DLC on Paradox Client(aka launcher v1) on Linux

That tab in the PDX client is pretty unreliable. If you launch the game there and look in the DLC tab of launcher v2, is it there okay?  

Can you uninstall the game, restart the launcher and then reinstall it? That should pick up on the DLC.  

Sorry about that, a bit of a glitch back here I think.

Please try again now!  

I just installed it on my Ubuntu installation, and with the tweak I made to your account Royal Court now shows in the Paradox Launcher v2 DLC tab. So it is not a Linux issue.

In the PDX client log out, then back in again. Then just run the game, does Royal Court show in the Paradox Launcher v2 DLC tab?  

Great to hear, sorry about the hassle, the hotfix was released late on Friday but I'm happy you got to enjoy the game during the weekend !
