I have a Jabra A320s bluetooth USB adapter that I use with my Phonak hearing aids. It was working great on Windows XP Pro. Not that I've upgraded to Windows 7 it no longer works. I have run the Install CD program that came with it and it prompts me the the driver does not have a recognized certificate. I press install any way but it keeps asking me the same.

Click on 'I don't have the disc. Show me other options' 5. Click on 'Browse my computer for driver software'. Browse to where you extracted the files and choose 'Next'.
Finally after I select do not install (driver) it continues with the installation. When I look at my installed devices it shows up but when I right click on the bluetooth icon in the tray it says no bluetooth device found.

I went to device manager to try and update the driver but it does not show up.
