Taken from the wikipedia page on the game: "Unlike its predecessor, Star Trek: Klingon, the PC version of Star Trek: Borg was intended exclusively for use with Windows 95 (the most common Microsoft operating system of its day). Thus, in order to disallow users of Windows 3.1, the OS and graphical settings of the user's computer are checked whenever the game is run. If anything other than Windows 95 running in 16-bit color mode is detected, the program terminates."

I verified this by trying to install on a Win 3.1 machine and ended up getting this exact message,
