It is not, I am sorry - MacOS and WIndows only.  

Right click on ck3.exe , properties, compatibility. Tick "disable fullScreen optimisations" untick every other box in that dialog, Apply and exit.
Then in the launcher Game Settings menu, select fullScreen display mode, Vsync off, refresh rate 60.

Is that any better?  

If you hover over that icon, it will tell you what it means. Most likely the latest save is from a previous game version.

What happens if you hit PLAY there exactly?

Can you start the game from ck3.exe run directly from file explorer?  

Any mods involved?

That aside I have no real idea what could be causing this to you, I am sorry. If these are not Ironman campaigns, can you at least reload from autosaves?  

As the only suported distro for this game is Ubuntu, I'm afraid this cannot be reported to the developers or worked on by them. Sorry about that!  

Looks like we still have a permissions issue here. What antivirus app do you use? You need to make sure all these apps are in its exceptions lists:

stellaris.exe and dowser.exe (in the Steam Stellaris folder)
C:/users//AppData/Local/Programs/Paradox Interactive/launcher-v2.2022.14/paradox launcher.exe (or whatever version is now latest there)
C:/users//AppData/Local/Programs/Paradox Interactive/bootstrapper-v2.exe

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

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

Lord Lukas said: I've redownloaded the game, didn't work.
I deleted all files from the folder, didn't work.

My guess is you didn't clear out all files and folders before reinstalling. Here's the full process:


- 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.

Garr Incorporated said: Could it be because of some weird way the launcher interacts with Steam being installed in a drive different from C:? I keep thinking about this being a thing despite it being very unlikely. Wish I could easily test it out without literally removing everything.

That is a normal situation; I have the launcher on C: and the game on D: and it works fine.  

Garr Incorporated said: That launcher, as before, doesn't see Stellaris.

That is expected; standalone mode is meant for users who don't want to use Steam, so it does not see your Steam installation. We're trying to diagnose and fix your launcher issue here which is unrelated to that situation.

As the launcher has run, there should be a cpatch.log now?  

Firstly, that message is misleading, you probably haven't really been logged in elsewhere. It's just a generic guess as to what the connection problem might be.

Are you having any general Internet slowness or unreliability?

Is this just while playing solo, or in MP too or only?  

The other poster here says "your specs are out of date and no longer supported now", which is untrue - the game has NEVER been supported on Macs with Intel video systems; it is just that by happy accident it used to run adequately on them, but no longer did in 1.29.

That said, this thread is over 3 years old and I can't say we're seeing other such reports now, so this situation may have been ameliorated by another happy accident. Do let us know if you give it a try now.  

Right click on the .exe , properties, compatibility. Tick the "run as Admin" box, untick everything else, Apply and exit that dialog.  

I don't know how it works but is disabling it enough to make sure it is not affecting the game? Or might it have to be uninstalled entirely?

That aside I'm a little short of ideas on this one, I see nothing here to cause this to you. Is this the same computer and Stellaris installation you had previously? If so it's worth deleting the Documents/Paradox Interactive/Stellaris/ folder (aside from any valued saved games) so the recent game version can write the caches again. And unload GeForce Experience before starting the game.  

This is a weird one, we really have nothing to go on! What happens if you set bootstrapper-v2.exe to run as the Windows Admin user then run it manually?  

What if you exit the Steam app entirely before running ck3.exe ?  

In what game please?  

Those logs look okay, but was there no cpatch.log in the same place?


Does this file physically exist?
C:/users//AppData/Local/Programs/Paradox Interactive/launcher-v2.2022.14/paradox launcher.exe

If so, what happens if you run in manually from File Explorer?  

We have three possible workarounds that may solve it:

Disable IPv6
- Close CK3
- Go to Control Panel > View Network status and tasks > Change adapter settings (left side)
- Find your Hamachi Connection and Disable it
- Find your Internet connection adapter (for me, it was WiFi)
- Right click your internet adapter and select properties
- Scroll down to find "Internet Protocol Version 6 (TCP/IPv6) and uncheck the box
- Select Ok
- Start up CK3 and should work.

Disable all other network adapters
Go to Windows Control panel.
Click on Network & Internet.
Click on View Network Status.
Quick Tip: You can also quickly access these settings by right-clicking the network icon in the taskbar and selecting the Network & Internet settings option.
Click on Change adapter options.
Right-click all network adapters that are not connected to the internet and select the Disable option.

burgunfaust said: launching thru the ck3.exe resulted in the same issue inside Steam that caused this tech request. No change.

I'm not quite following you here, as running it that way does not involve Steam at all, nor that CEF process. You are double clicking on ck3.exe directly in File Explorer, not using a desktop shortcut or something like that?  

From what you say here, the issue is with the launcher and not the game.


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/{userName}/AppData/Local/Programs/Paradox Interactive/
- C:/users/{userName}/AppData/Local/Paradox Interactive/
- C:/users/{userName}/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/{userName}/AppData/Local/Paradox Interactive/launcher-v2/
Please attach them here.
