If you are unable to configure and install drivers for your bluetooth device/adapter, then below is a simple tool to make this task easier for you.
Bluetooth Driver Installer is a small freeware utility which tries to install generic Microsoft driver for your Bluetooth adapter. The program is based on a widely known method of patching %WinDir%\inf\bth.inf file.
The program automatically creates a restore point before making changes to system.
How to use
1. Uninstall your existing bluetooth stack (driver software that came with the bluetooth adapter).
2. Reboot your computer and click "Cancel" when Windows asks for the driver.
3. Run BluetoothDriverInstaller.exe and follow instructions of the wizard.
