Microsoft Exchange Server 2007 setup cannot continue the Exchange Server 2007 upgrade because Microsoft Forefront Security for Exchange Server services are running on the local computer.
Exchange setup requires that the Forefront Security for Exchange Server services be disabled before the Exchange Server 2007 upgrade can continue.
To resolve this issue, disable the Forefront Security for Exchange Server services and then rerun the Exchange Server upgrade.
