Can't use bluetooth

I don't know why when I install the software, the following warning is shown"
Currently Microsoft does not have a certification program in place for
Bluetooth devices. As a result, at this time it is not possible to provide a
certified drivers for Bluetooth devices. In the event that Microsoft
implements a Windows Logo certification process for Bluetooth devices, signed
driver will be made available"

After the installation, when I start using the Bluetooth, it asks me to
provide the license file.

I really don't know why. Please help. Thanks a lot.
