I have a new Sony Vaio laptop with Windows 7 64-bit. Right out of the box, I could connect my phone and iPod touch 3g to my laptop with Bluetooth flawlessly.
My problem started since the last Windows update. I'm unable to use Bluetooth, my Computer says it can't connect to my devices because of a missing peripheral driver
Go to Start, searched for "bttray", and clicked open file location. Then i right clicked on "bttray" and made it compatible for Vista. I also performed the same operation for BTStack Server.
Thanks to Cam
