Europa Universalis IV Dev Tracker

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.  

We sometimes need to do that to get the launcher installed, but normally not to run it after that.  

I don't see nay cause for this in those files; you have only one sound output and it uses the default MS driver, not some third party one that might have such problems.

If you plug in a USB headset do you get any sound then?

Run the game up then alt-tab out to Windows. Right click on the Speaker icon in the Windows taskbar, open volume mixer. Scroll across to the game; is it set to mute or a very low volume?  

YuraO said: I posted similar message in a bug report section but got no response for a few days.

Most likely because it's not a game bug - if it were everyone would get it!



DXDIAG is a program you run from the Windows search box on the task bar. After running it will open a window and start collecting info with a progress bar in the lower-left corner. When it completes click the 'save all information' button and save it to a file then attach that file here.

depth453 said: Same problem here, just build my new PC with Win11, and keep getting the same error "MSIEA5D.tmp is not a valid Win32 application."
Manually running the launcher install msi files, same errors.
Is there any fix/work around for this issue?

Did you try posts #8 and #11 above?

If so can we get the logs from post #13 please.  

Please try this:

- uninstall Paradox Launcher v2 from the Windows "Apps and features" utility, if still present.
- if you have any trouble uninstalling , try this MS tool for that purpose:

Right click on eu4.exe , properties, compatibility. Tick "disable fullScreen optimisations" untick every other box in that dialog, Apply and exit.

Edit that settings.txt to say:

refreshRate=60

vsync=no

Then in the launcher Game Settings menu, select fullScreen display mode.

Is that any better?  

Please disable ALL mods while we work on this, and only on a new campaign that's never been modded, thanks.

From your Documents/Paradox Interactive/EU4/logs/ folder, attach here system.log , error.log .  

Does this also affect CK2, Stellaris, and HOI4? Or just EU4?

Does this happen right from the start in 1444? Or only in mid or late game play, or only after playing for a while?

Please attach here your Documents/Paradox Interactive/EU4/settings.txt and pdx_settings.txt .

If there are no mods involved, that sounds like a corrupted installation. Here's the complete clean reinstall process:

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

In particular make sure there are no files or folders left under either the Steam EU4 or Documents EU4 locations, before installing again.  

This is a cosmetic problem caused by a minor bug in the new launcher, the DLC is still available to you in the game.

It should be fixed in the next launcher update.  

This is pretty clearly a problem in your AMD video driver or card, I'm afraid:

Fault bucket LKD_0x141_Tdr:6_IMAGE_atikmpag.sys, type 0
Event Name: LiveKernelEvent

- uninstall that driver with this tool https://support.amd.com/en-us/kb-articles/Pages/AMD-Clean-Uninstall-Utility.aspx

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 Epic app entirely
- run EpicGamesLauncher.exe as the Windows Admin user
- run the game from the Epic client

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 eu4.exe directly from File Explorer, which bypasses the launcher.  

A launcher update cannot affect the names or contents of saved game files. Indeed it's hard to see how you could get a Paradox launcher update while playing, as the launcher is unloaded when the game starts!

So far as I know, there is no visibility into the Epic cloud storage, but you could ask them about that.

In general uncorrupting any computer file is like unscrambling an egg (ie impossible), but I suppose it is possible those files only have a minor glitch that some judicious editing could conceivably fix. The good folks over in User Mods probably have the most experience in editing save game files.  

This shouldn't impact your game though. I double checked and whilst I see the same in the launcher, in game it shows as owned and enabled. The launcher team is aware of this and looking into it.  

I get this too, seems to be a bug in the new launcher (weirdly!).

I'll report it now, sorry about that!  

I don't know what could cause that. If you rename those files to something sensible can the game then see them? They should end in .eu4  

We have three possible workarounds that may solve it:



Disable IPv6
- CloseEU4
- Go to Control Panel > View Network status and tasks > Change adapter settings (left side)
- Find your Hamachi Connection and Disable it
- Find your Internet connection adapter (for me, it was WiFi)
- Right click your internet adapter and select properties
- Scroll down to find "Internet Protocol Version 6 (TCP/IPv6) and uncheck the box
- Select Ok
- Start up EU4 and should work.



Disable all other network adapters

1. Go to Windows Control panel.
2. Click on Network & Internet.
3. Click on View Network Status.
   Quick Tip: You can also quickly access these settings by right-clicking the network icon in the taskbar and selecting the Network & Internet settings option.
4. Click on Change adapter options.
5. Right-click all network adapt...
