Back in the days on lan parties there was what we called "the russian version" that only had question marks in the installation dialog (Because of unsupported fonts most likely) which had Z-Bot included.

That's probably this one: https://archive.org/details/cs-1_6_z-bot

You had the fonts, but your system was configured for cp1250 or something like that, while the installer used cp1251. So it was a text encoding issue.
