mhicken,
This is an issue with your XML services on the computer. If you compare your Diagnostic Report to others on the forum, you will notice that yours is missing a bunch of text below the "Office Details" line. We commonly refer to this area as the XML blob. This is caused by a missing Registry Key and is most likely why the Product Key Update Tool did not work.
I will provide you the steps to resolve this XML issue, but I strongly suggest waiting for the Windows XP disk, that we have sent you, and conduct a clean install.
Fix (Part 1):
1) Click “Start” button, then “Run”
2) In the Run window, Type: regsvr32 msxml3.dll <Click OK>
(Note: This will register the msxml3.dll and the registry entry ‘HKEY_CLASSES_ROOT\MSXML.DOMDocument’ will be generated)
If this does not work, the msxml3.dll may be missing or corrupt. Follow the below Fix (Part 2), in that case:
Fix (Part 2):
1) Go to the Microsoft XML Parser (MSXML) 3.0 Service Pack 7 (SP7) download page at: http://www.microsoft.com/downloads/details.aspx?FamilyID=28494391-052b-42ff-9674-f752bdca9582&DisplayLang=en
2) From the files available, download “msxml3.msi”
3) Double click the file and follow the steps to install.
4) Click “Start” button, then “Run...”
5) In the Run window, Type: regsvr32 msxml3.dll <Click OK>
