What happens if you start the game through the launcher? Does eu4 open at least a window? Do you get a red triangle with the message "launching the game failed"?
If eu4 doesn't open a window and the launcher says "launching the game failed", it is usually because of one of the following problems:
  • you configured the game to run as administrator, but the launcher doesn't run as administrator. In that case disable the option to run the game as administrator
  • you have an antivirus or ransomware protection software that prevents the launcher from writing its files. In that case you have to add the launcher(and eu4) to the exception list of your software
    • If you have Windows Defender(also called Microsoft Defender), add it to the Ransomware "Apps Allowed Through" list(here are instructions for that).
    • If you have bitdefender, add the launcher to the list of ransomware exceptions and "give it access" to "protected files".
  • the launcher installation is broken. That can be can often be fixed by reinstalling the launcher:
    • On Windows, first use the windows uninstall function to uninstall "Paradox Launcher v2"(if it is there). And then delete the launcher directories:
      • C:/users/<UserName>/AppData/Local/Programs/Paradox Interactive/
      • C:/users/<UserName>/AppData/Local/Paradox Interactive/
      • C:/users/<UserName>/AppData/Roaming/Paradox Interactive/launcher-v2/
      • Documents/paradox interactive/.cpatch/
      • every directory in Documents/paradox interactive/ that starts with launcher-v2
    • In Linux delete the directories ~/.paradoxlauncher and "~/.local/share/Paradox Interactive/launcher-v2/" and the file "~/.local/share/Paradox Interactive/launcherpath"
    • In macOS delete the directory "~/Library/Application Support/Paradox Interactive"
    • Afterwards you can start the game from steam again to reinstall the launcher.
