[2020] CK3 crashes shortly after the start

Please update that nVidia driver:
Download Drivers | NVIDIA
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

www.microsoft.com

Download Microsoft Visual C++ 2010 SP1 Redistributable Package (x64) from Official Microsoft Download Center

www.microsoft.com

Download Microsoft Visual C++ 2015 Redistributable Update 3 RC from Official Microsoft Download Center

www.microsoft.com

Download DirectX End-User Runtimes (June 2010) from Official Microsoft Download Center

www.microsoft.com (run dxsetup.exe after extracting from this download)

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.


If none of that helps, please post new copies of all those text files, thanks.  

I think that VC++ 2015 needs further updating. Please go here:
https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads And run the x86 and x64 installers there.


If that doesn't help, strangely the nVidia driver only got updated to the second-newest one from November, not the latest December one. You might try a clean reinstall of it:

- uninstall the nVidia driver and all nVidia software
- reboot
- install the December one from here:
Download Drivers | NVIDIA - reboot again

Good luck!
