Have you installed OpenAl via oalinst.exe (Hotar\Dependencies)?
I have problems with most of the games I've downloaded from here. Windows 10, AMD A6-5200 APU with Radeon. 8gb ram. Anything specific you'd like to know? I tried to install, and it said a newer one was already installed. That shouldn't matter should it? Or does it depend on something that's in an older version that's not in a newer version?
