It does run for me, and pretty stably. I am having an issue with character's faces though, I imagine it has something to do with my DLC's. I have every one of the DLC's/Expansions besides Sons of Abraham, should I turn my face DLC's off to fix it? Specifically the issue is with the hats and accessories being off their intended position (such as a hood floating in the air next to the character's model).
EDIT: Also, am I right to be copy pasting it directly into my Crusader Kings 2 folder? It doesn't have a mod file or anything to pick up for the launcher, and a clean install is a click away with Steam.
I'd recommend just creating your own folder and .mod file -- it's easy, just create a new folder, rename it, then copy-paste a .mod file, and edit it with Notepad++ or something.
