I have searched and carried out instructions from folks on forums about this issue before reaching this brick wall and posting!

An install from the user guide will not work (same problem as many are having, license problem, device no device found etc).

I have tried patching the Widcomm BTW system files, tray icon turns white but no device found.
I have tried editing BTWUSB.ini using VID/PID information gained from USB:
I have tried Installing different Widcomm releases and driver cominations.
I have even re-installed Windows with different Service pack levels up to SP1

The driver in device manager always shows as WIDCOMM with the relative level but when earlier BTW is installed the device shows as bluetooth audio (re-installing drivers here does not solve the problem).

Any advice here would be appreciated greatly
Thanks in advance,
