If you end up with an NRG file, just download AnyBurn and convert it to an ISO file, open the ISO with Windows Explorer, this will mount the 'CD', run the setup, after setup, go to Program Files x86 via Windows C: Now what I got out of this was a folder called Classic Gaming, this is where Blood installed to, as long as the ISO is mounted, the game should work, like most PC games of the 90s, you'll have to run it with DOSBOX, the easy way to do this is to drag the exe file (In this case Blood.exe) to the DOSBOX shortcut which I insist you keep on your desktop
