Hello Peter,
Thank you for your response.
What is the make and model of your computer?
I would suggest you to install the Windows 8 Bluetooth drivers in compatibility modeand check.
Follow these steps to install the drivers in compatibility mode.
a. Download the Bluetooth drivers from the manufacturer’s website.
b. Right-click on the driver and click on ‘properties’.
c. Click on the ‘compatibility’ tab and check the box ‘Run this program in compatibility mode for’ and select Windows 8 operating system from the drop down.
d. Click on ‘Apply’ and click ‘OK’ and run the file to install it.
