I'm not sure if this is what you are looking for, but you might look here, [URL] to see if this is what you might need.
I upgraded to Windows 7 today and got the message "Your Bluetooth Software license does not include use with this Bluetooth device :emotion-14:." I can see the 590Plantronics in the "Bluetooth Headset Operations and Settings" window but it would not connect.   I looked for and installed the latest driver for Windows 7 on the Dell driver downloads site "Widdcomm Bluetooth Software 6.2.0.9600". When it installed it gave a "Device unplugged" message for four instances of "Bluetooth Peripheral Device" but despite a "Ready to use" message for "Bluetooth Hands-free Audio" the overall message is "Device did not install properly" and I still cannot connect to my P590 headset.  Any idea what I am doing wrong or where I can I get the correct drivers? Thanks
