Someone who bought King's Bounty: Dark Side can tell me that polish language is avaiable in game?

I haven't got this installed at the moment so can't check properly but went over to my library to look and the only installers available are English, German and Russian so I'm guessing no.

After looking into the game's files, I found that there are some Polish files in the game's code. Unfortunately, I think the necessary files to run the game in Polish are missing.
