Don't see “Bluetooth Radios” and bluetooth not working on Bootcamp Windows 7 I attempted to ask this question at superuser.com but so far I have not received any help. 
So for the past couple of days I've been trying to get my Logitech Dinovo Bluetooth Keyboard working on my Windows 7 partition. Unfortunately it is not finding any bluetooth devices. I have no issues whatsoever on the OSX partition so I know it's not a hardware issue. Additionally, it seems that I can find Bluetooth settings when I right-click on "Apple Internal Keyboard and Trackpad" but when I try to "Allow Bluetooth devices to find this computer" I receive this error. I also don't see the Bluetooth icon in the system tray.

This issue has been really frustrating so any help would be great!
Perhaps there has gone something wrong with installing the Windows supporting Software. You can try re-installing this by using your installation discs, or you can download it on the software page on the Apple website.
