Ckii won't start

[7thGalaxy]

As in title,
Ckii won't start - it has worked for years and years, and now I can't even get the mod selection/game launcher to open.
If opened in steam it says preparing to launch, but gets no further, the box closed.
I have:
-completely uninstalled then reinstalled Ckii, having deleted both my user/paradox/ckii folder and the one in steamapps to make sure it is clean.
-followed the advice to try the lower screen resolution 640 X 480, the game still doesn't load

I have recently changed my motherboard and processor but everything else works fine.
I use Windows 10, pro
I have excluded the entirety of my games folder in steam from windows defender. I've had windows defender for years and have had no trouble though

Thanks

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.

In particular make sure there are no files or folders left under either the Steam CK2 or Documents CK2 locations, before installing again.

THEN Install ALL these Microsoft modules:

(run dxsetup.exe after extracting from this download)


Also if you have installed RadeonPro, or a gaming VPN app called Evolve, or the MSI Gaming App, or Duet, disable it as it clashes with this game.


If that doesn't help:
Please attach here Documents/Paradox/CK2/settings.txt
From your Documents/Paradox/CK2/logs/ folder, attach here system.log , error.log and exceptions.log
