Hi,
I am getting this message :
"Could not activate key: An unknown error occured when communicating with Steam."
when trying to activate game in my paradox account -- any solution ??
 
We can see EU4 is already registered to your account here, its icon is under your name here.

So I'm not sure what you mean by "trying to activate game in my paradox account" as no activation is necessary as such - you don't even need a Paradox account to run the game. Can you clarify what exactly you are trying to do, where?

As depict in picture below, when i pushed activate (green button), those message in purple box appears. I already linked to steam in this paradox account.

All of this because of launcher v2 prematurely end, some people in thread suggesting to link steam account to paradox account in order to avoid prematurely end sympton - so i tried it.

Next question, i am able to extract launcher v2 through zip file (instead of windows installer) - is there any manual step where to put the exctracted files ... in order to succesfuly install launcher v2 ??

Thanks,

That page is for redeeming a Steam key you bought from Paradox into your Steam account. As you already have the game in your Steam library there is no need to do it again. The Steam error you are getting will be something like "key already redeemed".

That function has nothing whatsoever to do with the ability of the Paradox launcher to to install and run.


Please try this:

- 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.

- exit the Steam app entirely
- 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.
