(I use Windows 7 64-bit)

First off, is this site safe? http://dege.freeweb.hu/

Some of the zip:s are flagged as malicious by Chrome? Real threat or false alarm?

Anyways, I've already tried installing it using GliDos, but it doesn't work...

I have set the emulation mode to DosBox, and when I start the game a big window called Glidos Server (or something similar) appears.
Inside this window I get some sort of Redguard loading screen, with a rotating logo. The whole thing seems to lag a lot. Then The window becomes black except for a small logo (from Redguard) in the upper corner. Then the program crashes.
It looks like this just before crash: http://i197.photobucket.com/albums/aa253/GrandDukeAdense/nammelas_zpsbdf92628.jpg

If anyone knows how to solve this GliDos issue, I'd like to know.

If not, I must know if "Dege's stuff" is safe, because I need that for another possible method to run Redguard!
