His launcher is old and has failed to update itself.

Please try this:

- exit the Steam app entirely
- uninstall Paradox Launcher v2 from the Windows "Apps and features" utility, if still present.

Delete the following folders if still present:

- C:/users//AppData/Local/Programs/Paradox Interactive/
- C:/users//AppData/Local/Paradox Interactive/
- C:/users//AppData/Roaming/Paradox Interactive/launcher-v2/
To see the AppData folder you'll need to enable View Hidden Items in File Explorer.

- run steam.exe as the Windows Admin user

- run the game from the PLAY button in Steam

Are you sure he deleted all those folders?

In this folder are some .log files:
C:/users//AppData/Local/Paradox Interactive/launcher-v2/
Please attach them here.

I've seen this caused by Windows not being on good internet time. Have them go into the Time&Date control panel and make sure Set Time Automatically is ON. Then hit the SYNC NOW button.

Then. do the process in post #2 again; they may have to exit and rerun the launcher a couple of times for all updates to apply .

All the best!

Launcher is still stuck on old version, hard to see why now. Let's try forcing an update of the launcher.

Download the installer package for Windows: https://forumcontent.paradoxplaza.com/emailsignatures/2021.1-win-prod.zip

Unpack the file you just downloaded and place the three files in the Steam folder for the game you're having issues with. If asked if you want to replace already existing files click "yes" - that's a sign you are in the right place!

Then please repeat the launcher reinstall procedure from before.

Good luck with that!
