--- Comment #20 from Rosanne DiMesio dimesio@earthlink.net --- It appears twice in the registry:
[HKEY_CLASSES_ROOT\TypeLib{F5078F18-C551-11D3-89B9-0000F81FE221}\5.0\0\win32] @="C:\Program Files (x86)\Common Files\Microsoft Shared\OFFICE11\msxml5.dll"
[HKEY_LOCAL_MACHINE\Software\Classes\TypeLib{F5078F18-C551-11D3-89B9-0000F81FE221}\5.0\0\win32] @="C:\Program Files (x86)\Common Files\Microsoft Shared\OFFICE11\msxml5.dll"
The file is in that location.
