Unfortunately, can not be installed on Windows 7, the supplied software. The installation fails always with the error message: ". You do not have a valid license to carry out CSR Harmony Please contact your supplier" I turned both to the seller and to the manufacturer. To date part of the support is no reaction. The device is therefore completely useless. The Windows Bluetooth standard drivers support the adapter is not complete, so fails to connect to a Phillips SHB9100 headset.
