I make it a habit to go to the Microsoft site at least once a week to check if there are any updates. I have had ZA Pro 6.1 for about 6 weeks and, while I can go to the Windows Update site, scan and download updates, the installation always fails. I am getting pretty concerned because I know there are several updates (not to mention a new version of the updater) that I have not been able to install.
I see from some previous posts that other users have come up against this problem before. Any advice re what to do about it?
