How can I change language to Russian in NA Steam version?

For M&MH7 I can see Russian language supported with full audio on the store page :

However when I go to steam settings I can see all supported languages except for Russian:

The game is bought in North America steam store, I can also see it in my Uplay account, but no language preferences there.

Any fix for this?

I ended up installing Unofficial Community Patch, which has optional language packs. Unfortunately, it has translations only for text data, no audios are included.

And this patch also fixes some annoying bugs - like Vampires not being able to drain health. So it's better to install it anyway.
