What is the location of a vanilla CK3 installation?

[Zediwan]

I am confused to what is meant with that? What location do I need to enter?

• ...\Steam\steamapps\common\Crusader Kings III\game
• ...\Steam\steamapps\common\Crusader Kings III
• ...\Paradox Interactive\Crusader Kings III

If you're using it for CK3 (Crusader King's 3), put the file path for the game's install location. That's just showing the common paths.
