The game itself, at least with language set to Polish or English, still displays it's version in the right lower corner as '1.12.08'.
If it can't read its version (Maybe due to wine not supporting it) it will display a static string which is built into the exe. Which does sais 1.12.08 because i forgot to update it.
Note: I only managed to start the Russian campaing, as the American one results in another crash (as soon as the introductory video starts, the screen get's black and only sound can be heard), but this COULD be a Wine, not the game's bug. Nevertheless, no such problem existed with vanilla GoG installation (version 1.10 if I recall correctly). Also, constantly hitting Escape, so that the video can't even start, allows me to successfully start the first mission in the Am campaign.
