You can get the original russian GOG installers via magnet links at freegogpcgames
Just scroll down the front page to the updated section, should be towards the top of the list.
edit: if this is a new source for people, afaik it’s safe, I’ve been using them for years. I scan everything with BitDefender and it doesn’t throw up any flags. Probably one of the sources for the InsaneRamzes GOG releases that get repacked on a regular basis.
edit: “russian GOG installers” just means it also includes that language option
