My computer keeps telling me I have updates to install - there are 15 which all relate to Office 2003, which I am currently running on Windows Xp Pro SP2. When I try to install the updates, they all fail, yet when I shut down I'm told that 1 of 15 updates is installing, then 2, etc. through to 15, then the pc shuts down. The next time I boot up, I still have the update shield in the tray and it's still for the 15 Office2003 updates. How can I get this sorted?
