Finally, I got the update via Live Update. I rebooted as requested and see that the new version is in the Help About screen, and the the Engine, Branding, and MUI folders all have a folder for the new version (actually, the engine has both the old and the new - anyone know why this is?).
Bad news - tried to connect to Live Update following the reboot, and am getting a message "Unable to connect to the Norton Live Update Server. Please check your internet connection". Clicking on More Info displays the same message along with the numbers 8921,253.
Is there another problem with the Live Update Server, or is this a new bug connect with the update?
Obviously, since I am writing this, I have Internet connectivity.
