I imagine that if the people who were having problems are still having those problems, they would have subscribed to this thread and can speak for themselves.
It turned out that the one person (Barbara Meek) that had received the update, when she thought that she should not have because she was using Office 2010 Professional, actually also had Office 2010 Starter installed and it was for that reason that she received
the update notice.
If you yourself have a problem, other than with the way in which the Update Notice was delivered, then, if you provide full details, you may receive assistance.
