Steam Runtime Communication Error

[ULLtimir]

What can i do with this error

 

[FlattestGuitar]

Same problem. Started seeing it yesterday. I can't launch the game when I click "Ignore" and try to play it.

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 HOI4 from the PLAY button in Steam

Good luck with that!

You could start by explaining your problem in detail, and what games are involved, please.

That really should fix that problem. Are you sure you deleted all those folders and ran Steam as Admin?

Please delete the ~/Library/Application Support/Paradox Interactive/ folder. To see it go to the Finder, hit command-shift-G (ie Go To) and paste in ~/Library/Application Support/ . Then run the game from the PLAY Button in Steam, to reinstall the launcher.

If that does not get the launcher running, we will need these files from that same folder:

Attach ALL .log files Found here ~/Library/Application Support/Paradox Interactive/launcher-v2

 

[magnusf]

Thanks. Removed the launch folders but that did not fly.
How/Where can I send you the log files?

 

[AndrewT]

Attach them right here please.

 

[magnusf]

Ok, pls find the log file here

 

[AndrewT]

Let's try forcing an update of the launcher.

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

Where can I find the Steam folder?

 

[AndrewT]

Where can I find the Steam folder?

Right click on the game in your Steam Library, manage, browse local files.

 

[magnusf]

Problem solved. Thanks.
