I'm using OptiPlex 3040; Win7 SP1 64 bit;
I'm trying to connect my BT headset (Beoplay H9) using the built-in Bluetooth, and every time I'm trying I get an error.
I've tried to get a BT dongle, connect it and got errors when trying to install the drivers.
I've tried a different computer (same model) and all worked perfectly.
Please mention the error message that pop-ups on your computer.
Have you checked it by updating the bluetooth driver?
