I recall the msxml log telling me that it did not support nodes with node type 8 (comments node), and the installation failed thereafter, but that was some time ago. I don't know if our msxml was updated since then. The Office installer stores a digital signature in a xml file inside a comment. I think that the installer then reads the sig and validates something.
No, the exact problem is stated in comment #6.
