It looks like Ravenloft: Strahd's Possesion....but I can't quite tell. the image is kind of small...
On second thought, it looks like a Realms of Arkania game. I never played the series but I remember seeing screenshots that looked like that.
It's not any Ravenloft game, but the genre's right.
The game is out of reach at the moment, so I must stick to this rather small screenshot.
