I fought this on two machines, for CSR Cambridge Bluetooth May 2008.
Finally, this worked
1) In Device manager I did an uninstall and delete driver files (sound
drastic, but there are other copies)
2) I did a scan for hardware changes, so the dongle driver file
reinstalled
3) I hit retry on Windows Update, and this time the install wen
through, or I got lucky.
The related bluetooth dongle was in place throughout. If the dongle i
out, the update is "not needed", and you get either an error or a fals
good install.
Of course, this update does not fix the CSR dongle by itself. That i
a secondary puzzle. Some bloggers say the vendor cut old devices off i
the later releases, perhaps because there were too many old designs fo
which they did not get license fees
