[2023] Eu4 visual c++ visual launching error

moved to Tech Support  

That error is almost always a missing or bad Microsoft DLLs. Odd thing to happen out of the blue if you've been playing on the same machine without significant change. When did it last work for you?


Try this Windows repair tool:

Did you run that repair tool? If so did it find anything to fix?  

In the Windows Control Panel uninstall Visual C++ 2010 and 2015/17/19/22 - there may be several instances of each.

THEN Install ALL these Microsoft modules:

Atahan009 said: I have the visual c++ 2005 and 2008 aswell can there be a problem about that?

No, the game does not use them.

We have one more shot before we have to contemplate a clean Windows reinstall. I'm afraid this is a bit of work, but please delete this list of files (about 50 in total)

C:\Windows\SysWOW64\mfc100.dll
C:\Windows\SysWOW64\mfc100u.dll
C:\Windows\SysWOW64\msvcp100.dll
C:\Windows\SysWOW64\msvcr100.dll
C:\Windows\SysWOW64\msvcr100_clr0400.dll *
C:\Windows\SysWOW64\xinput1 3.dll
C:\Windows\System32\mfc100.dll
C:\Windows\System32\mfc100u.dll
C:\Windows\System32\msvcp100.dll
C:\Windows\System32\msvcr100.dll
C:\Windows\System32\msvcr100 clr0400.dll *
C:\Windows\System32\xinput1 3.dll

* you may need to change user permissions on these two files before you can delete them. If they won't delete, don't worry about them

PLUS all files that fit the pattern d3dx9_??.dll in both those folders; usually about 20 in each. Then re-run those 6 installers above, PLUS

Black screen with pink elements after launching the game

I've purchased today EUIV and have difficulties with running it. After using steam launcher I see only black screen which turns into pink shapes and nothing else happens (however I hear music). Attaching screen , DxDiag log and EU error log. Are... forum.paradoxplaza.com
If so, no, that is nothing to do with DLL files.  

Your Documents/Paradox Interactive/Europa Universalis IV/logs/system.log file will show which video system the game is using.  

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 .  

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
fullScreen=yes
borderless=no

vsync=no

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


Does that help? If not, go into the nVidia control panel, Manage 3D settings. Force eu4.exe to run on the "integrated Intel" option, save and exit. Does that work better?
