Interesting. I also instaled the game using offline istaler, and it isn't instaled on C: too, and its save folder path is
pcpotato459: My game is not installed on C drive but instead installed on a separate partition. So the offline installer save location for me is D:\Program Files\GOG Games\Serious Sam 4\UserData\0\SeriousSam4\SavedGames.
I suppose the save folder path depends on the game instaled not the instalation method
