FIX: Office 2007 Installer – The windows installer service cannot update one or more protected windows files.
I came across an interesting dilema just now trying to install Office 2007.
Before actually starting to install the product the setup stalled with:
The windows installer service cannot update one or more protected windows files.
I was a little stunned, this is clean installed box. So I checked the Event Viewer:
Product: Microsoft Software Update for Web Folders (English) 12 -- Error 1933.
The Windows Installer service cannot update one or more protected Windows files. SFP Error: -536870654.
List of protected files:rnc:program filescommon filesmicrosoft sharedweb server extensions40binfp4autl.dll
Ah ok, this is a customised installation of windows (I’ll post how this happend later) and its looking for the frontpage extensions which (in this install) doesnt exist. So how to fix? Simple, download a copy of the missing file from DllDump, place it into the c:program filescommon filesmicrosoft sharedweb server extensions40bin folder and retry installation!
