Update for Outlook Junk Email Filter 2003 (KB936643) Security Update for Office 2003 (KB936048) Security Update for Excel 2003 (KB940602) All 3 of these updates were failing for me. I installed the ActiveX component from the Office Online Download page (http://office.microsoft.com/en-us/downloads/default.aspx) like it was suggested on other forums, same result. I tried downloading the updates directly from Microsoft and that didn't work either. However, when I downloaded the updates directly from Microsoft and tried to install locally, I got this message: "Error 25090. Office Setup encountered a problem with the Office Source Engine, system error: -2147023838. Please open C:\ program files\ Microsoft Office\ OFFICE11\ 1033\ SETUP.CHM and look for the "Office Source Engine" for information on how to resolve this problem." This gave me an idea. I went to "Services' (START > RUN > type in "services.msc" without the quotes) and saw that at some point I must have disabled the "Office Source Engine" service. I set the service back to automatic and started the service. I then went back to the Microsoft Update site and the 3 updates installed fine. I have also read that certain anti-virus products may prevent these updates from installing properly.
