Microsoft® Exchange Server 2007 setup cannot continue because Microsoft Core XML Services (MSXML) 6.0 is not installed on this server.
For all Unified Messaging server role installations, Exchange 2007 setup requires that MSXML 6.0 be installed on the computer to support Microsoft speech services.
To resolve this issue, install the MSXML 6.0 software from http://go.microsoft.com/fwlink/?LinkId=70796 and then rerun Exchange 2007 setup.
