I posted this in the office area as well. With respect to updating Office XP Software, I continually receive an error message regarding the program. I searched all the data base info here on this site and followed instructions in the archived areas of this site on how to clean upthe registry files to get OfficeXP (albeit I have Office XP Professional SP1) to allow me get the updates or at the very least uninstall and try again. I was successful in getting the windows installer to allow me to uninstall and reinstall. Curiously after the reinstall, the windows installer briefly appears then the application in this case Word opens. When I go to the office update -- after I cleaned out the reg files; temporary internet files; history files, etc., it freezes again at 40% and once again I receive the following error message: "The Office Update site is unable to check for updates on this computer. This may be happening because of one of the following reasons: You do not have administrative privileges for this computer. There is a network problem and the detection catalog used by the Office Update site failed to download. Go back to the Downloads home page and try running detection again. Windows Installer patch files (.MSP files) from previously applied Office updates are missing from the \Windows\Installer hidden directory on your computer. MSP files are stored on your computer after update installation completes because they need to be referenced for future update operations. If the files are missing you will not be able to apply Office updates. You may also be unable to uninstall Office products as a result of the same problem. Please contact Microsoft Product Support for assistance. You installed Office updates in the past and then upgraded from Windows Installer version 1.0 to Windows Installer version 1.1. For more information see the KB article Windows Installer May Prompt for Install Source if Unavailable. " I cannot get the updates for Office XP Professional SP1 -- no matter what I do... HELP!
