I managed to get it running fine by using the latest version of dgVoodoo, and among the 4 .exe's in my PRG_ENG folder, only launching 2 of them works. (EngRelManuallyDeploy19v19.exe + EngRelNo3d.exe)
Launching the game through the EngRel 3d Fix &Extreme Camera zoom & Overhead Map.exe or EngRel.exe still gives the same error.
I recently installed Warhammer: Dark Omen, which was a game i absolutely loved when i was a kid.
I followed the guide best i could and also used the mod pack registry files. And disabled antivirus. Yet my game colors are all wrong or black. (As seen in attached file)
