I have a problem with this launcher, my game won't start up, because of "some kind" of Steam problem.

[Theonrad]

Hi there!
I can't play my game, cause it says there is trouble communicating with Steam, however all the places i checked, Steam is running and communicating. All of my stuffs just keeps verified, but nothing happens. If i ignore, it keep telling me there is an "unknown error from Steam" and that it. I can't start my game or anything. I checked the same with Hearts of Iron 4, Victoria 3, Stellaris... all of them working, only this one's not.

Thaks for the help in advance!

You should be able to start the game from eu4.exe directly, although you may not be access to the DLC when run that way.


As for that error, it seems to be a launcher problem - except that those other games all use the same installation of the same launcher!


Could you please do the following? It will generate a debug log that the launcher team can use to "deep dive" into what actually happens with the launcher.

• Right click the game in question in Steam > Properties > Launch Options
• Paste in this: --pdxlDebug
• Run the game
• Once it fails to launch, locate the logs in the following place

%LocalAppData%\Paradox Interactive\launcher-v2\logs\
(example: C:\Users\{user}\AppData\Local\Paradox Interactive\launcher-v2\logs\)

And attach them here, thanks.

Hi! I attached the yesteday's one too, it may help. I don't know. I hope i sent the correct ones.

I'm afraid not - .json files are not logs, and the other one is the standard log not the detailed log.

They should have names like launcher-2023-01-19.log

correction: these are actually empty files and i can't attach them properly

I can see at least 3 files that match my description, with >0 bytes, in that screenshot ... ?!?

This looks different to the other cases we're looking into, despite similar symptoms:

2023-01-18T14:26:07.551Z (pid:70276) error [SteamService]: Failed to initialize Steam API: Error: Steam initialization failed. Steam is running,but steam_appid.txt is missing. Expected to find it in: ~\AppData\Local\Programs\Paradox Interactive\launcher-v2.2023.1.1\steam_appid.txt

That steam_appid.txt file does not exist on my system for this game either yet it works fine - I can only guess you have a bad installation somewhere along the line!

Let's try a clean reinstall of Steam, launcher and game:


- move any valued save games elsewhere
- "uninstall" in Steam-EU4
- exit the Steam app entirely
- manually delete both the Steam/SteamApps/common/EU4 AND Documents/Paradox Interactive/EU4 folders

- 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.

- delete everything in the Steam folder EXCEPT steam.exe and the SteamApps folder
- run steam.exe AS THE WINDOWS ADMIN USER to rebuild all that
- re-install game in Steam, run a Steam Verify when done.
- add EU4.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list.
- start the game with no mods active and test

Good luck!

Yeah, that worked! Thank you for your help, i really appreciate it. I wasn't the best client, there a lot of misunderstanding on my side, but thanks again!

Is there any quick solution rather than uninstalling the whole (steam,game and launcher) ? It consume a lot of time and energy.
Maybe just wait 6 month until paradox fix the bug .... and everything will run/updating smooth again (been there)

You haven't replied here before; the above recommendation was to a different person who may well have a different problem cause than you do.

If you supply the logs I asked for, we can tell if you have same problem as them, in which case the above steps are necessary; OR you have the more common different problem, for which there is no current solution.

My problem is the exact same as posted in this thread - first page --- "steam runtime communication error" happen after launcher upgraded automaticaly.
But hey i found another way without uninstalling.
Just kept the steam running online ... run eu4profilling.exe from steam/steamapps/common/Europe Universalis IV/ folder ...
It will run the game smoothly and loaded all DLC.
