Crusader Kings 3 Dev Tracker

Can you start these games directly from their .exe files in File Explorer? NOT from the desktop shortcut.


FOr the launcher, 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//AppData/Local/Programs/Paradox Interactive/
- C:/users//AppData/Local/Paradox Interactive/
- C:/users//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//AppData/Local/Paradox Interactive/launcher-v2/
Please attach them here.  

Please update your nVidia driver to August 2022 https://www.nvidia.com/Download/index.aspx?lang=en-us

THEN do a full **clean** re-install:

- move any valued save games elsewhere
- "uninstall" in Steam-CK3
- manually delete both the Steam/SteamApps/common/CK3 AND Documents/Paradox Interactive/CK3 folders
In particular make sure there are no files or folders left under either the Steam CK3 or Documents CK3 locations, before installing again.
- re-install game in Steam, run a Steam Verify when done.
- add CK3.... Read more

Is that save started under 1.6.1.2 or the current patch?

If the former, please revert to that game version in the Steam betas tab for this game. If the latter, please post that save in Bug Reports here, thanks!

works on version 1.5.1.1 but none after which makes me think it is still the avx issue. processor was released in 2019, supports avx and avx2, but doesn't support avx512 which i don't know if that's what paradox is running.

Then you have an unrelated problem. Please make a new thread here with full system details and problem history, thanks.  

That settings file looks like the game never really started. I don't know why that would be!

My best guess is there is a Windows problem getting in the way here, although I see no sign of what that might be in your dxdiag.


Please install and run the free utility Speccy. Send its output to a text file and attach that here, thanks.  

bighendo said: same. pretty annoyed

Did you read my post immediately above yours?  

Okay; what happened then?  

What happens if you now run ck3.exe directly from File Explorer, any error show then?


Please attach here your Documents/Paradox Interactive/CK3/pdx_settings.txt .
From your Documents/Paradox Interactive/CK3/logs/ folder, attach here system.log , error.log , exceptions.log  

blockgaming06 said: no but downgraded to version 1.6

Sorry, I'm not sure what you are saying here. Can you clarify please?  

In the Steam Betas tab for this game is a new 1.7 beta to fix an issue with AVX. Please try that beta, does it help you?  

Does this Mac perhaps only have an Intel video system? if so that is the cause of your problem as that is not supported hardware for this game under MacOS, and since 1.6 it does prevent the game from even starting.

If that is the situation all you can do is revert to 1.5..1 , or run 1.6.x under Windows in Apple Bootcamp if you have that installed on this machine, or only play on any other computer you might have access to with supported hardware.

Sorry for the bad news!

SundoFox said: And in the game pass?
Do I now have to quickly play through my saved game every time you announce a new update? I'm really pissed off because so many hours are just gone

Unfortunately MS do not provide a way of us distributing old or alternate game versions, so I'm afraid it is possible this will happen again with future major updates.

HOWEVER I've just had some indication that 1.6.1.2/1.7 were supposed to be save game compatible! And were tested as such, but perhaps some configurations (eg combinations of DLCs, say) may be the pr... Read more

In the beta channel there is now a new 1.7 with AVX fix included. Please opt into that, does it help you?  

Drackn said: Do you have any fix for the Gamepass version?

MS provide no mechanism for us to distribute alternate or old game versions, so I'm afraid you'll have to wait until a formal patch. Sorry about that!

That problem does not occur in MacOS. You have an unrelated problem, please start your own thread. Thanks.  

Have these mods been updated yet to work properly under the new 1.7 patch?

You say you've only had this problem a few days, yet older versions of this game now cause this to you. IOW game versions that used to work on this machine now do not - would you agree with that? If so that has to be some local issue.

There is actually a slightly later nVidia driver (473.81) than the one you mention above, may as well try that
