Installation

So I downloaded the 1.12 version, unzipped it and put it in the following folder:

C:\Program Files\2K Games\Firaxis Games\Sid Meier's Civilization IV Colonization\MODS

But for some reason when I load the MOD (with the AoDII v. 1.12 in the upper right) I don't have any new maps, new civilizations or anything. I haven't tried playing it yet to see of it works regardless but shouldn't I be able to play as Pirates or play on different maps? Just curious what I did wrong.

Sounds like you have an extra folder. Open the Mods folder, then the AOD2 folder and look inside. If there is a folder called "AgeOfDiscoveryII" then move THAT folder down one to the Mods folder.
