Exchange Server 2010 setup cannot continue because a previous setup failure occurred while uninstalling a server role.

Exchange 2010 setup requires that a failed server role uninstall be successfully uninstalled before any other setup task can continue.

To address this issue, uninstall the failed server role(s), and then rerun setup.
