xbox wireless controller adapter

I just got an xbox wireless adapter for windows to connect my controller to my pc but it's not working. I installed the drivers and nothing. I uninstalled and let windows check for drivers and the adapter doesn't even show up as a recognized device. I have windows 7, AMD Athlon II x4 64, 1TB hdd, and plenty of ram so I know my pc is compatible. I'm starting to wonder if I ordered a defective unit any tips or ideas? I even tried installing the drivers manually from the install cd.

For Windows 7:

Right click on Computer
Go to Properties
Click on Device Manager
Right click on the Unidentified Device
Go to Properties
Go to the Drive tab
Click on Update Driver…
Browse my computer for driver software
Let me pick from a list of device drivers on my computer - Microsoft Windows Common Controller for Windows
Update Driver Warning
Click Yes

I just plug it in and it works. I'm sure you have the latest update for 'Microsoft 360 Accessories', right?

Edit: 1.2 is the latest version.
