Eu4 won't start anymore after reinstalling

[Urloc the Great]

I recently reinstalled Eu4, but when I wanted to start the game it didn't start. Not even the launcher. I click on "play" in steam, steam says "playing" for a few seconds, a submenue for starting options pops up and when I pick "play EU4" it goes back to nothing. Like it won't start at all. I even tried loading some older patches like the 1.30x ones but they didn't work either.

Make sure you verify your files.

Changing the EU4 version has no effect on whether the launcher will start. They are separate applications.

What happens if you run eu4.exe directly from File Explorer?


As to the launcher issue, 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 Steam app entirely
- 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/{userName}/AppData/Local/Paradox Interactive/launcher-v2/
Please attach them here.
