I didn't do anything differently. I went to the BS5 folder in GOG Downloads and clicked on Application.
(Actually, I think it says Setup.)
Then I checked the box that said I'd read the Eula, which I hadn't, and hit Launch the game.
In case it means anything, I'm playing with Win 7 Pro, 64 bit.
Ummm...did you get it from Steam?
I'm seeing on the Chat at Revolution that people are having problems starting the game with Steam.
Revolution says they're working on it.
Ah, well, dumb me.
You said you got it from GOG.
