I have installed Windows 7 on MacBook Pro using BootCamp. Usually when turning my Bluetooth headset on and trying to pair it with Mac for the first time, Windows fails to install the drivers and opens a solution in Action Center, which suggests to download the driver from the Broadcom webpage. This used to work for me before, drivers were installed and everything worked well. However now, when I start the driver installer, it would get stuck at "Detecting Bluetooth Device" stage. There is also a warning with text, which says "Please plug in or turn on your Bluetooth device":

I have tried turning my headset on/off, bringing it into pairing mode, installing/uninstalling device to/from the Bluetooth Devices. None of these worked. Any ideas?
