Unfortunately, bumping your thread does not work because we see there has been a response and think someone is looking into it. In this case I have spotted it and will add it to my list of threads to work on. However, please continue to be patient.
I have seen some reports of where the Server Core App Compatibility FOD tool has been added that it will cause problems like these. Do you have this installed? If so try uninstalling it and then try the update again.
