Microsoft® Exchange Server 2007 setup cannot continue because Microsoft Windows Media Audio Voice Codec is not installed or a more recent version of Windows Media Audio Voice Codec is available.
Exchange 2007 setup requires that you install the most recent version of Windows Media Audio Voice Codec on the server. Windows Media Audio Voice Codec is needed to support the Exchange Server 2007 Unified Messaging server role.
To resolve this issue, install the most recent version of Windows Media Audio Voice Codec from http://go.microsoft.com/fwlink/?LinkId=67407 and then rerun Exchange 2007 setup.
