How do you install a mod?

[name thief]

I downloaded the CBM mod into a folder called mods. That folder is in the folder called dominions3. Which is in the program filesfolder, and which is in Local Disk (C located in My Computer.

In the mods folder there is a file with a zipper on the side. I open the file and click on the extract files button opening another screen with near idintical contents. Returning to the mods folder a new folder is present.

When I open Dominions 3 and click on preferences followed by Mod preferences. Nothing shows up except a box with only an exit button and a title.
