This method is a little... extended... but it's the one I use. DK works beautifully, but you might need to learn some new (valuable) skills.
 
Download DOSbox from here. Open dosbox.cfg in the DOSbox directory with Notepad and delete everything in it. Replace it with this:

Code:

The C:\ in DOSbox will be C:\Documents and Settings in Windows. Install Dungeon Keeper Gold on your desktop (or anywhere in Documents and Settings). Run the DOS version with DOSbox.
 
You'll need to know some basic DOS:
 
"cd desktop/doody" (w/out the quotes) would change your directory to C:\desktop\doody (since C:\ is documents and settings). You can use "\" or "/".
 
DOS doesn't understand spaces or words that are too long. Don't use spaces in folder names, and if a word is too long, type the first six letters followed by "~1". Like this:
 
XXXXXX~1
 
To run a program (.exe, .bat or .com files), type its name. If the program is Fear.exe, type Fear.
 
dir will list the contents of a folder. Hit tab over and over to cycle through these contents (you don't have to type dir first).
 
Learn more about the config file from DOSboxwiki (use google) and the DOSbox website. You can customize it to your liking, but this version should work.
 
If you have a newish 3D card, change output to direct3d and pixelshader to point.fx.
