I don't know why that would be, but the nVidia driver is definitely the problem here! Please contact nVidia support to get past that (IMO false) error.  

You have a problem with your AMD video driver:

Fault bucket LKD_0x141_Tdr:6_IMAGE_atikmpag.sys, type 0
Event Name: LiveKernelEvent

And it dates from 2015. Please:

- uninstall it with this tool:

- install the latest from here:

To be honest it's not something I've tried or looked into until now. Certainly searching for Paradox launcher gets lots of hits.

Looking at the screenshots you sent in more closely, the file patches there are weird - instead of the usual slashes between folders you have a Yen symbol. Any idea why that might be, is there something unusual in this Windows setup?

DXDIAG is a program you run from the Windows search box on the task bar. After running it will open a window and start collecting info with a progress bar in the lower-left corner. When it completes click the 'save all information' button and save it to a file then attach that file here.  

This should be the right one:
NVIDIA DRIVERS GeForce Game Ready Driver WHQL
AFAIK they dont' discriminate between sub-versions of Windows 10?  

Don Lionheart said: Yea, they neglected to tell us that 1.2.2 is not compatible at the moment with 1.3. If you want to load your 1.3 save on Steam, opt-in to the beta program and it works.

The patch notes for 1.3.1 say that patch will help with some cases of this, so try opting into that beta!

However the OP has never been able to run the game once, so 1.2.2 saves cannot be his problem.  

The Lord said: I managed to start the game by running ck3.exe, instead of trying to start it via Steam.

So from Steam you never see our launcher, is that right?

If so, Please try this:

- exit the Steam app entirely
- 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/

4orchids said: I also have this issue. It started after the Corvus patch. No one in our multiplayer campaign has bought the Northern Lords DLC.

Please make a new thread in Bug Reports, and attach the save there that causes it, plus any OOS logs you can find on the host's machine.

Sorry about that!

How did you check? Because yours is from Feb and the current one is from March:

Please try the following:

- unsubscribe from all mods
- delete the folder Documents/paradox/CK3/mod/
- delete the file Documents/paradox/CK3/mods_registry.json
- delete the file Documents/paradox/CK3/launcher-v2.sqlite

Add CK3.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list. You should add steam.exe and C:/users//AppData/Local/Programs/Paradox Interactive/launcher-v2.2021.1/paradox launcher.exe to that list.

- subscribe to a few mods
- run the game up and see if those mods are now available to you.

I hope that does it for you!  

In the game launcher please set Display mode to windowed.

THEN go here:

The latest supported Visual C++ downloads

This article lists the download links for the latest versions of Visual C++. support.microsoft.com And run the x86 and x64 installers there.

IF that doesn't help, Has the game ever run OK on this computer? Or never?

I don't know then. Have you tried searching the registry for it?

In Task manager-processes do you see any of these?

msiexec.exe
cefprocess.exe
dowser.exe
bootstrapper-v2.exe
paradox launcher.exe  

Please delete the ~/Library/Application Support/Paradox Interactive/ folder. To see it go to the Finder, hit command-shift-G (ie Go To) and paste in ~/Library/Application Support/ . Then run the game from the PLAY Button in Steam, to reinstall the launcher.

If that does not get the launcher running, we will need these files from that same folder:

Attach ALL .log files Found here ~/Library/Application Support/Paradox Interactive/launcher-v2/  

I don't know why this is happening to you, I have to admit!

You don't want to update Windows?

See if there is a fix in the next patch 1.3.1 when it becomes public.

If not, I guess you should make a new thread in Bug Reports with a save showing the issue under that patch.

Sorry abotu all that!  

Sorry but I can't help with gameplay advice, I don't actually play this game. Please try the main forum!  

I've had one report this is due to the new DLC Northern Lords. Do you still get this if you start a new game, where the host has that DLC disabled?  

In the game launcher please set Display mode to windowed.

IF that doesn't help, Install ALL these Microsoft modules:

Download Microsoft Visual C++ 2010 SP1 Redistributable Package (x86) from Official Microsoft Download Center

I see you have a UI overhaul mod active. Does this happen when there are no mods at all in use?  

imax9000 said: Assumed? What? You guys don't have one lousy test machine to actually, you know, test it?

We didn't need to test it as it appeared to come good without us changing anything. My assumption was that was due to something Apple fixed.
