Download Bluetooth, huh?
Bluetooth is a technology for transferring files/communications. You can't really "download it". You can, however, download the appropriate drivers for your Bluetooth card so that it works correctly. Figure out the model number of the card, and look it up at the manufacturer's website. Look for the drivers for W7.
