Steam Runtime Communication Error

[AndrewT]

Could not locate a valid installation of the Paradox Launcher open C:\Users\userl\AppData\Local\Paradox Interactive \launcherpath: The system cannot find the file specified.
Detailed logs can be found at: CAUsers WseMAppData \LocalWaradox Interactive \launcher-v2 \launcher-dowser.log
If the error persists, please contact support at link

It gave me that when I tried to redownload paradox launcher, can you help me?

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.

Let's try forcing an update of the launcher.

Download the installer package for Windows: https://forumcontent.paradoxplaza.com/emailsignatures/2020.3-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!

- run steam.exe as the Windows Admin user

- run HOI4 from the PLAY button in Steam

Good luck with that!

Now I can't even get to the point I was with the error occuring.

... okay, so what DO you see? Are there any log files at all there now?

Hello sir! The game forces me to do this every month, this is so frustrating. What should I do? I get this error on ALL Paradox games when I get it on single Paradox game.

Every month is about how often there are new launcher versions, could that be it?

Of course the launcher should update itself without needing to be reinstalled.

I keep having this issue on Windows 10, I've tried uninstalling and deleting the folders specified. Simply restarting steam seems to solve it but it's frustrating having to restart steam every time I want to launch a game, Prison Architect in my case. The link posted in April doesn't seem to be valid any more so I've been unable to try that. I've attached the log files and would appreciate any help to resolve this.
