The 1603/1605 errors we see there are typically a previous other installation stuck, or a problem in the Windows update/install processes.

If you see msiexec running in Task manager-processes, kill it and try this launcher install again please.

Otherwise run the Update app in Windows, does it load okay, find anything to apply - whether a patch, update, or whole new Windows 10 version? If so do that and reboot, then try this launcher install again please.

If still no good, do you see Paradox Launcher v2 in the Windows Control Panel to uninstall? If so does it uninstall cleanly, or get an error doing that? You can use this tool to remove it properly:

Please try the following:

- unsubscribe from all mods in BOTH the Steam Workshop and the Paradox mod site mods.paradoxplaza.com
- delete the folder Documents/Paradox Interactive/CK3/mod/
- delete the file Documents/Paradox Interactive/CK3/mods_registry.json (if present)
- delete the file Documents/Paradox Interactive/CK3/launcher-v2.sqlite (if present)
- run the game up and check the launcher is okay with no mod or other errors
- 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!  

What version and checksum show in the main game menu?  

What antivirus app do you use? You need to make sure all these apps are in its exceptions lists:

eu4.exe and dowser.exe (in the Steam EU4 folder)
C:/users//AppData/Local/Programs/Paradox Interactive/launcher-v2.2022.1/paradox launcher.exe
C:/users//AppData/Local/Programs/Paradox Interactive/bootstrapper-v2.exe

IF that doesn't help, also set each of those .exe files (EXCEPT eu4.exe !) to run as the Windows Admin user.

Then the game should run from Steam/our launcher, and enable all the DLCs.

Good luck!  

You can't build the shuttle hub until you research it. Do you see it in your tech tree?  

Looks like nVidia stopped updating the driver for that card last year, that's a shame.

While I doubt it is the cause of your problem, can you do a test with a colony with no mods at all enabled?

Assuming that does not help, it looks like a Windows or nVidia hardware problem, to me. Do you have any overclocking active?  

Neither game requires connection to us at all to start, so I very much doubt it is an issue here.


In the game launcher please set Display mode to Borderless. THEN go here:

Please edit your Documents/paradox interactive/ck3/pdx_settings.txt file. Find the rendered paragraph and change it as follows:

"renderer"={
version=0
value="OpenGL"
}

Then test with a new campaign - do you see the same problem?


Also, please check with Acer for an update to that 2018 Intel video driver, failing that Intel themselves:

That error log shows a problem in the tutorial alright. What happens if you don't do the tute, go into the game proper?  

That second screenshot shows the download for the standalone Paradox client, aka launcher v1. That is a separate application for a different purpose, is nothing to do with your problem, so you can ignore that.

launcher-installer-windows.msi is in your Steam-Stellaris folder.

In your quote from my clean install process you have missed the most vital step., which is running steam.exe as the Windows Admin user. Please try that.

IF that doesn't help, in this folder are some .log files:
C:/users//AppData/Local/Paradox Interactive/launcher-v2/
Please attach them here.  

There is a new launcher 2022.1 out today - did that trigger the need to do it again?  

You have a problem with your nVidia card or driver:

+++ WER0 +++:
Fault bucket LKD_0x141_Tdr:6_IMAGE_nvlddmkm.sys_Kepler_UserOC, type 0

Please try this:

- uninstall that driver and all other nVidia software
- reboot
- install the 2022 one from here:

That dxdiag reports two separate crash issues with ck3.exe , really not sure what could be causing that for you.

If you exit the Steam app entirely then run ck3.exe directly, does it still happen?

When you did your clean reinstall, did you make sure there are no files or folders left under either the Steam CK3 or Documents CK3 locations, before installing again?  

Looks like we still have a video problem. But what we did really should not have stopped the game from launching altogether!

That is usually an antivirus app getting in the way. What antivirus app do you use? You need to make sure all these apps are in its exceptions lists:


CK3.exe (in the Steam CK3/binaries folder)
dowser.exe (in the Steam CK3/launcher folder)
C:/users//AppData/Local/Programs/Paradox Interactive/launcher-v2.2021.10.1/paradox launcher.exe
C:/users//AppData/Local/Programs/Paradox Interactive/bootstrapper-v2.exe

IF that doesn't help, also set all those .exe files (EXCEPT ck3.exe !) to run as the Windows Admin user.  

When you say you can't earn achievements, is that because you cannot get into Ironman mode? Or what exactly is happening in that regard?

If you click on the Achievements icon in the game does it show they are gettable?  

I'm not aware this is a general problem. Are you on the Steam edition of the game, or a different one?

If the Steam one are you using crossplay to play MP?  

mac2636 said: Does Paradox understand what an absolute pain this is? Having to Unsubscribe from all mods then going back and finding them all again to re-subscribe is such a royal pain. Will this issue ever be corrected or a simpler workaround be implemneted?

That process should only need to be done once. Are you seeing otherwise?  

Are you all on the Steam or other edition of this game? Or mixed?

When you start this game there are three MP options, all players need to pick the same one. Have you tried all 3?  

I suspect you are right. Sorry for that outcome!  

That logs stops at the point of detecting the video system, so I'm fairly sure that is the problem here.

Unless you have access to a machine with supoorted hardware, please seek a refund from wherever you bought it.

Sorry about that!
