'Something went wrong while updating the launcher.'

[Fumbly]

So I googled this problem, and followed the things they told the others to do. Nothing worked so far.
I even installed the game, still cant update .. I can play the game, but not play the mods

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/<UserName>/AppData/Local/Programs/Paradox Interactive/
- C:/users/<UserName>/AppData/Local/Paradox Interactive/
- C:/users/<UserName>/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

IF that doesn't help, in this folder are some .log files:
C:/users/<UserName>/AppData/Local/Paradox Interactive/launcher-v2/
Please attach them here.

Note that you can run ck3.exe directly from Windows Explorer, which bypasses the launcher.
