Hi, Ryland. Just "New" a shortcut to "Snowblind.exe" and richt-klik it, switch to the "Shortcut" tab, append " -setup" (with a leading space and excludes double quotes) to the string of "Target" like this:
"D:\Games\PROJECT - SNOWBLIND\Snowblind.exe" -setup
That's it. Otherwise, after installed this game using original disk image, you'll get this shortcut in the "Start Menu" (\Eidos\Project Snowblind\Setup.lnk).
