Microsoft Exchange Server 2010 Setup cannot continue because an update is required for the mechanism that displays MMC snap-in context Help topics.
Exchange 2010 Setup requires that you install the MMC snap-in context Help mechanism update that is referred to in Microsoft Knowledge Base article 951725.
To resolve this issue, install the update 951725, "An update that extends the mechanism for displaying snap-in context Help topics is available for the MMC in Windows Server 2008" (http://go.microsoft.com/fwlink/?linkid=3052&kbid=951725), and then rerun Exchange 2010 Setup.
