No, not exactly that, but the same result. If I run the exe (in Crusader Kings III/Binaries) as administrator I get "The application was unable to start correctly (0xc0150004). Click OK to close the application" The launcher does not work, it only gives me "The game failed to launch" When everything fails you begin to look for alternatives to address the issue. So far I've had no luck at all. It's heartbreaking, because I played the game in March successfully, but since then I've replaced my dead gpu with a new one, and now cannot play (only this) Paradox title.
In future please start your own thread, thanks, as intertwined conversations about multiple issues get confusing for everyone!
That's not a common Windows error with our games, but try running the Windows Update app, see if it finds anything to update. If so do that and reboot.
Then please run this Windows repair tool:
Describes how to use the System File Checker tool to troubleshoot missing or corrupted system files in Windows 8.1, Windows 8, Windows 7 or Windows Vista.
See if that finds anything to fix.
