If you are experiencing problems with the HoI4 launcher, please check our troubleshooting page.

If you are having issues with Kaiserreich that you can't pin down, it may be worth doing a clean install of both Hearts of Iron 4 and Kaiserreich.

  1. For the love of all that is holy please use a legal copy of HOI4
  2. Ensure you aren’t on any beta branches of HOI4
  3. Delete HOI4 in steam
  4. Go to your HOI4 folder (normally C:\Steam\steamapps\common\Hearts of Iron IV)
  5. Delete folder "Hearts of Iron IV"
  6. Go to C:\Users\NAME\Documents\Paradox Interactive\Hearts of Iron IV
  7. Delete everything that isn't a save game
  8. Reinstall HOI4
  9. Wait for Kaiserreich to download
  10. Make sure you play with no other mods (music mods aside)

Note: Running the game in admin mode may help if you are still having issues
