I have updated from Leopard to Lion. As a result, I couldn't open old Word Documents (.doc). So I reinstalled Office version 2011, which seems to have fixed the problem. Now I cannot update Office. If I run "Software Update" I am told that all software is "up to date". If I go to Microsoft's home page and try to download SP 14.0.1 and 14.0.2 Service Packs I am told that there is a critical element missing and the updates cannot be installed on my hard disk. I have also re-installed the Microsoft AutoUpdate but to no avail. Any clues?
