Crash fix and now no launcher and no CK2. Win 10. Help!

  • Crusader Kings III Available Now!

    The realm rejoices as Paradox Interactive announces the launch of Crusader Kings III, the latest entry in the publisher’s grand strategy role-playing game franchise. Advisors may now jockey for positions of influence and adversaries should save their schemes for another day, because on this day Crusader Kings III can be purchased on Steam, the Paradox Store, and other major online retailers.

    Real Strategy Requires Cunning


Dec 20, 2020
After a long time of toruble free service. CK2 started crashing regularly at the turn of the next game month.
This 'may'(?) have come after a windows update but it had been a long time since I'd played so am unsure if it's a direct cause and effect.
I followed some advice from the forum:

"Please do a full **clean** re-install:

- move any valued save games elsewhere
- "uninstall" in Steam-CK2
- manually delete both the Steam/SteamApps/common/CK2 AND Documents/Paradox/CK2 folders
- re-install game in Steam, run a Steam Verify when done.
- add ck2game.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 CK2 or Documents CK2 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."

However, after deleting the Documents/Paradox/CK2 folders the launcher has disappeared and the game won't start either from steam of the game.exe Reinstalls of the game files don't bring the Documents/Paradox/CK2 folders back and now the game won't launch. It brigns up a the dialogue box that comes justr before the launcher but then everything stops and it returns to as if you'd never hit the button.

I've gone from a crashy CK2 to none at all. Help appreciated. Thanks is advance.
Logs and dxdiag attached.

This may or may not be related to this game problem, but you have a serious memory issue:
Memory: 8192MB RAM
Available OS Memory: 4088MB RAM
That's almost certainly faulty memory, but can be CPU or system board.

This game does not use the Paradox launcher so I'm afraid those launcher log files don't help us.

What happens if you exit the Steam app entitrely and run ck2game.exe directly from Windows explorer? Any error show then?
