Can't Reinstall, Repair or Update MS Office 2003

Whenever I try to repair, uninstall or reinstall MS Office 2003, I get the message, "The patch package could not be opened.  Verify that the patch package exists," etc.  Another symptom:  When I run Excel, I get a couple of "Preparing to Install" messages before the program opens.  Finally, the MS Office Update site tells me that it "is unable to check for updates on this computer."

I would appreciate help.

There is also a Windows Installer CleanUp Utility to uninstall the failed product.
Check out dspent's link above.
I take it that you already tried reinstalling the patch or Service Pack 1
I would recommend completely removing the office program and reinstalling from scratch

 just get a copy of "Your Uninstaller! 2004" (

You get a trail period for free.  This will not only remove office 2003, but will clean out any registry entries etc. allowing a completely new install.  Again if there are any third party addins that office is using the link to these will be removed.

Ideally remove office using the above program, go to and make sure that your window OS  is fully upto date.  Then reinstall office and then go to to check for updates

Hopefully that should sort it out

1.  I tried reinstalling SP1; same problem installing it as with all other operations.

2.  I ran "Your Uninstaller! 2004" and tried to use it to uninstall Office 2003.  After "uninstalling" Office 2003, nothing seems to have changed:  Office 2003 is still on my computer, and all the same symptoms persist.
Try this......

Click Start, and then click Run.
In the Open box, type regedit, and then click OK.
In Registry Editor, locate the following registry key:

On the keyboard, press the DELETE key.
When you are prompted to do so, click Yes to confirm the deletion.
Quit Registry Editor.

Then remove Office and finally reinstall it if desired.

This may also help you a great deal....;en-us;290301

Your installer may be corrupt in which case you may want to reinstall from here (option #2):

Once you've replaced your installer try uninstalling Office 2003.
