Bluetooth Audio with Bootcamp on Macbook Pro
On my MacBook Pro 17” with Windows 7 32bit – I had only to download the:
Updated Bluetooth® for Windows® software at

this small software will do all to you, find, download and install like a miracle.

On my MacBook Pro 13” with Windows 7 64bit wasn’t that easy.
Just download the above driver from the apple forum:

After unzipping I only had to run the Bluetooth_Suite_win7.EXE file, reboot the computer and my SoundLink Mini was installed correctly!
