Europa Universalis IV Dev Tracker

We are having trouble with Avast and our new launcher 2021.1 , although not necessarily this exact issue. Add eu4.exe to the exceptions list of Avast. You should add steam.exe and C:/users//AppData/Local/Programs/Paradox Interactive/launcher-v2.2021.1/paradox launcher.exe to that list. You may need help from Avast support in how to allow those apps through fully.

The same may apply to other antivirus apps.

Let me know if that helps!  

In the game launcher please set Display mode to Borderless.

IF that doesn't help, Please do a full **clean** re-install:

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

Also if you have installed RivaTuner, RadeonPro, or a gaming VPN app called Evolve, or the MSI Gaming App, or Duet, disable it as it clashes with this game.

How can you have disabled OneDrive on MacOS, if I can ask? I thought it was Windows only.

So you never see our launcher, is that right? If that is the case, AND eu4.app does not start the game, you apparently have two separate problems.


LAUNCHER:
Let's try forcing an update of the launcher.

Download the installer package: https://forumcontent.paradoxplaza.com/emailsignatures/2020.16-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 delete the ~/Library/Applica... Read more

The only private channel we use for support is our ticket system. But if you've found a third party app that is contributing to this, well, all I can say is stop using it!

You could report it to them too of course.  

Are you on the standard public Steam client, or have you perhaps opted into Steam's beta program?  

grotaclas said: My guess is that the crash is from the steam networking code. Maybe it gets passed an invalid pointer from eu4/ck2.

But why would that be from just this one user? After all everyone is using the same Steam and game code!  

I see, very hard to understand what could be causing this for you.

Do you have access to any other machine, either in that location or elsewhere, to test this problem on?

You mention shutting off a firewall, I assume that was the Windows Defender one. How about in your internet router/modem?  

You say "currently" - it hasn't always been like this for you? If that is so, what change or update occurred in your system and network between the last time you could play MP okay, and the first time this happened?

What happens when you try to host?

Our similar game Crusader Kings 2 is now free to play on Steam, does it have the same problem?  

Can your friend play this game with some third person without this issue?

Any chance you can try it via a VPN? Or from a different machine or even from a different network?  

The last major update of EU4? I guess that would be 1.30 released on 9 Jun 2020 - you've had this problem ever since then, over 6 months?

You should check that all the required Steam ports are allowed through all your firewalls, as the new eu4.exe. in that patch may not be in your firewall exceptions lists:

Has this always happened ever since you've had this game? Or only since when?

Does this also affect our similar games Stellaris, CK2, and HOI4? Or only EU4? because they use the same MP services as EU4.  

Hey there!
At the moment there's no easy way to disable specific DLC as the subscription service is built by Steam. It's something we've requested though and will hopefully be possible in the future. However you can do this with some manual work by following these instructions:



1. Find the file "dlc_load.json", usually located in "C:\Users\your_username\Documents\Paradox Interactive\Europa Universalis IV"

2. Right click it and select Edit (this can be done in any text editor)

3. To disable DLCs, add them to the "disabled_dlcs" list



For example if you want to disable Fredmans Midsummer Epistles and the Sabaton soundtrack, this is what your file should look like:

{
"disabled_dlcs":["dlc/dlc065_fredmans_midsummer_epistles/dlc065.dlc","dlc/dlc052_sabaton_soundtrack/dlc0...

Simply deleting the folder I mention in post #2 really should fix that. It will also delete the log files, so if they are still there I guess we need you to try deleting that folder again.  

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//AppData/Local/Programs/Paradox Interactive/
- C:/users//AppData/Local/Paradox Interactive/
- C:/users//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//AppData/Local/Paradox Interactive/launcher-v2/
Please attach them here.

Note that you can run eu4.exe directly from Windows Explorer, which bypasses the launcher.  

Please try putting the game language into English. That should let you get past that crash.

All the best!

HOI4 and Stellaris will install the game launcher. But I assume they have the same problem?

Really, GPU only goes up by 2c? A bit surprising, but temperature is obviously not the problem here anyway.

What is, I frankly have no idea now. In Task manager - performance, are you seeing CPU, GPU or disk IO issues there when these ticks happen?  

The other case like this I'm running here just said that the problem did not occur under 1.28.3 with AA disabled, so you two obviously have a different problem cause.


Please report the temperatures of your CPU and video (GPU)
1/ before starting the game up and
2/ after say 30 minutes' play.
If your PC's vendor has given you no way of reading temperatures, install

I just had a report from another nVidia user on a similar game, who had this until they turned off anti-aliasing - can you try that please?  

I'm not familiar with Norton 360 but do make sure all these games are in its exceptions list.

I see you have OneDrive running, has it perhaps grabbed the Windows User Documents folder?


A few apps and utilities in there I'm not familiar with:

EarTrumpet.exe
SteelSeriesEngine3.exe
and all those Pivot Portrait apps/utilities

Can you try unloading those and see if that helps at all?
