Unable to start game

[mxancl]

When I try to start the game, eu4.exe started successfully but then died (I check it through Task Manager). I didn't use any mod, just use pure vanilla environment to start eu4. My windows is dev version (Build_26063.ge_release.240216-1326), before I updated my windows to it, I can start the game. error.log is empty
What can i do to fix this issue or what other information i need to supply?

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

Edit settings.txt to say:

refreshRate=60
fullScreen=yes
borderless=no

vsync=no

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


IF that doesn't help:
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.

Please attach here your Documents/Paradox Interactive/Europa Universalis IV/settings.txt and pdx_settings.txt .
From your Documents/Paradox Interactive/Europa Universalis IV/logs/ folder, attach here system.log , error.log , exceptions.log

I tired the method but it didn't work
The error.log is empty and I can't find exceptions.log in logs folder

As you can see in that dxdiag the game is crashing on dxgi.dll . I'm not 100% sure of what that DLL is but it is clearly part of DirectX,so a core Windows module.

This game only uses DirectX 9.0c so first try this installer

Download DirectX Redist (June 2010) from Official Microsoft Download Center

The Microsoft DirectX® End-User Runtime installs a number of runtime libraries from the legacy DirectX SDK for some games that use D3DX9, D3DX10, D3DX11, XAudio 2.7, XInput 1.3, XACT, and/or Managed DirectX 1.1. Note that this package does not modify the DirectX Runtime installed on your Windows...

(run dxsetup.exe after extracting from this download)

Then this one

And run the x86 and x64 installers there.

If still no good, try this Windows repair tool

It doesn't work. I think this problem is caused by the update because the modification date of dxgi.dll fit the date I update my windows
But thanks for your help!

I think this problem is caused by the update

A Windows update, you mean? Or something else?

A Windows update, you mean? Or something else?

windows update

Well I suppose that is possible, but OTOH that would affected every Windows 11 player, which we are not seeing - as yet anyway!

[IMPORTANT NOTE FOR GAMERS – UPDATED!] Some popular games may not work correctly and cause a bugcheck (green screen) when launched on the most recent Insider Preview builds in the Canary Channel. Please be sure to submit feedback in Feedback Hub on any issues you see with playing games on these builds.

 

[AndrewT]

Ah yes, well, our games are not written or tested on beta or preview OSs, so that could well be the problem here. Do report it back to Microsoft, of course.

All the best!

Hi! I've the same problem. I managed to play the game with all DLCs launching eu4_profiling.exe, I don't know if this workaround may work also for you, or if it's not ok for some reason.
Hoping that Microsoft releases a bugfix as soon as possible
