Put the DelugeDark folder in C:\Program Files (x86)\Deluge\share\themes
Edit gtkrc which can be found in C:\Program Files (x86)\Deluge\etc\gtk-2.0
The first line says gtk-theme-name = "DelugeStart"
Change it to: gtk-theme-name = "DelugeDark"
and save.
Credit goes to a couple fellows on the official Deluge forums.
