I've got a very annoying and frustrating problem. Every time I switch on my PC, the "Updates are Ready for Your Computer" icon appears in my system tray. When I click to install the updates, the installation starts. The problem is, during the installation of the first update, a message appears, saying: -"Microsoft Office Professional 2003 The feature you are trying to use is on a network resource that is unavailable. Click OK to try again, or enter an alternate path to a folder containing the installation package 'PRO11.MSI' in the box below."- If I click "OK", a shorter message appears, telling me to find PRO11.MSI again. If I click "Cancel", the update fails. The same thing then happens with the next update, and then the next update, etc., until I go through all of the updates. Here are the updates that keep failing: UPDATE FOR OUTLOOK 2003 (KB943649) SECURITY UPDATE FOR ACCESS SNAPSHOT VIEWER 2003 (KB955439) SECURITY UPDATE FOR MICROSOFT OFFICE 2003 (KB92159 OFFICE 2003 SERVICE PACK 3 (SP3) SECURITY UPDATE FOR MICROSOFT OFFICE POWERPOINT 2003 (KB94898 SECURITY UPDATE FOR OFFICE 2003 (KB945185) UPDATE FOR MICROSOFT OFFICE 2003 (KB978551) SECURITY UPDATE FOR MICROSOFT WORKS SUITE 2005 (KB943973) SECURITY UPDATE FOR MICROSOFT OFFICE OUTLOOK 2003 (KB945432) SECURITY UPDATE FOR MICROSOFT OFFICE 2003 (KB953404) SECURITY UPDATE FOR MICROSOFT OFFICE PUBLISHER 2003 (KB950213) SECURITY UPDATE FOR MICROSOFT OFFICE WORD 2003 (KB954464) SECURITY UPDATE FOR OFFICE 2003 (KB95447 SECURITY UPDATE FOR MICROSOFT OFFICE EXCEL 2003 (KB955466) UPDATE FOR OFFICE 2003 (KB907417) UPDATE FOR MICROSOFT OFFICE OUTLOOK 2003 (KB953432) As you can see, they are all related to Microsoft Office Professional 2003. I understand that all I need to do is provide the path to PRO11.MSI when the first message appears. However, I can't find the file anywhere on my computer. And I do not have the Microsoft Office Professional 2003 installation CD. The program came pre-installed on my computer. Nor do I have a repair CD of any kind. How can I fix this problem? If it can't be fixed without the installation CD, how can I stop Windows from trying to install these updates, without switching off Automatic Updates? I have tried clicking "Custom installation", then unchecking the updates, before checking "Don't notify me of these updates again," but it doesn't work. Help! It's driving me crazy! I use Windows XP Pro with Service Pack 3. Microsoft Office Professional 2003 came with my PC, pre-installed, licensed and perfectly legal. I bought the PC about 4 years ago. I haven't played with anything at all recently. The only thing that I have done is install and then uninstall Windows Live Messenger. Could that have caused the problem?
