Is it 220.127.116.114?
If you have it installed, i guess there are 2 ways to find out:
- Check the main game folder for a readme file, it usually mentions game version.
- Start the game, change it to windowed, the blue bar at the top of the window often mentions the version of the game running.
Not 100% sure, but works for most games. ;)
(ofc, if you want to know without installing, that doesn't help)
