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.
