[2021] Launcher/game issues

What is the nature of your issue with the launcher, pelase? You don't seem to specify. Does it run at all? If so what version shows?

In this folder are some .log files:
C:/users//AppData/Local/Paradox Interactive/launcher-v2/
Please attach them here.  

Ah, in that case you don't have a launcher problem at all most likely. If you run eu4.exe directly from File Explorer does it start up?


If not In the game launcher please set Display mode to Borderless. THEN go here:

The latest supported Visual C++ downloads

This article lists the download links for the latest versions of Visual C++. support.microsoft.com And run the x86 and x64 installers there.


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 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.

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.

IF NEITHER OF THOSE 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/EU4/settings.txt and pdx_settings.txt .
From your Documents/Paradox Interactive/EU4/logs/ folder, attach here system.log , error.log .  

Did you want your documents to be stored on the MS cloud? If not it is best to undo that, as it can get in the way.

What happened when you ran eu4.exe directly from File Explorer?

And you may as well do a clean reinstall and update of that nVidia driver:
- uninstall it and all other nVidia software
- reboot
- install August 2021 from here:
Download Drivers | NVIDIA - reboot again

good luck!  

It is a thing with the current game version that running eu4.exe does not show the DLCs. The point of doing that was to see if it ran at all, as a diagnostic step.

So we now know that you can run eu4.exe but the launcher cannot, for some reason.


What antivirus app(s) are you now using? You need to make sure all these apps are in its exceptions lists:

eu4.exe and dowser.exe (in the Steam EU4 folder)
C:/users//AppData/Local/Programs/Paradox Interactive/launcher-v2.2021.6/paradox launcher.exe
C:/users//AppData/Local/Programs/Paradox Interactive/bootstrapper-v2.exe

Good luck!  

Alright, now right click on each of those .exe files (EXCEPT eu4.exe!) and go to properties, compatibility. Set them to run as the Windows Admin user.

That should do it for you!
