27' iMac 2012 Wi-Fi not working in bootcamp

I installed Windows 7 Professional on my Mac and used the Boot Camp Support Software 5.0.5033 from here http://support.apple.com/kb/DL1638.

All of the drivers except the Nividia driver installed successfully. (That one I had to venture inside the folder and manaully install it).

I checked Device Manager and under the Networking Devices section, all of the Broadcom stuff appears as they are installed, but Windows still does not recognize the Wi-Fi card. I uninstalled and reinstalled the driver, but that didn't seem to do anything. I looked throughout the list and there is one missing driver for a Z77 Chipset that seems to not have been installed. I'm not sure if that is something that is affecting the system. Could that be a cause to the problems?

It all works fine on the OSX side if that info helps.
