Dude, don't use Glidos. You can use dgVoodoo for free.

I've tried that a multitude of times, with no success :/
I have no idea of why it won't work, might have something do with Vista, or some interfering applications.
I've played around a bit more with VPC, and concluded that I can't get anything Elder Scrolls related properly. Hopefully there exist some other application, with similar functions, but intended for games. I've heard of a few, but never found them, but if I ever do find them, and manage to get it running properly I'll remember sure to post it in this section of the forum,
EDIT:
I got a bit pissy today, because of this, and I really want to play Redguard and Battlespire. I tried Battlespire again, at first I had the same result, but then I started fiddling around with the settings a bit more than I've ever done before, and actually managed to get it running :blink: but the problem is that it's just on the center of the screen in a small area, while everything around is just black. It's playable, but damn small.
I also managed to get Redguard running in the Glidos trial, though I had to use something called VDos32, but at least it worked.
EDIT2/3:
@CrossL:
When I think about it, I haven't tried installing Redguard since before I upgraded my computer, so I might get it running with that now :shrug:Didn't work :meh:
EDIT4:
Found a Dosbox CVS build, that could run Battlespire properly. I'z happy! :trophy:
