[2023] Can't lunch the game and missing mods

Can you run those games from ck3.exe and aow4.exe directly from File Explorer?  

Texa-Glorious said: can launch ck3.exe, but aow4.exe gives error message "EOS_ Invalid Auth"

That should be fixed in an update to the Epic version a day or two ago. Did you get that?


As for the launcher issue with CK3, I'm not sure what could cause that. 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.

It has been months since I last played ck3, and the first thing that happened when I started, of course, was that I was asked to close and install the new launcher. (I also installed a bunch of new mods, if that makes any difference, which I suspect doesn't). When I restarted the game, everything went fine, but after exiting the game, Steam thought the game was still running. I tried closing the game using the "stop" function in Steam, but that just hung up on "Stopping." All that was left at that point was a complete reboot.

I can still use ck3.exe to start the game, but I do occasionally need the launcher as well to reorder the load sequence of my mods, some of which require a particular load order. It would be nice to do so without always having to do a reboot as well!

Sorry, I don't mean to hijack the conversation -- I just wanted to add another notice about the launcher.

As your symptoms are quite different, please start your own new thread in future, thanks.
