Most installers provide a "Repair" option that will check to make sure binaries are where they are supposed to be and Windows registry entries are valid. Customer would like this capability in our installer, particularly the Windows installer.
Customer would also like to be able to upgrade an existing installation using the installer (or a separate upgrade installer).
Customer is currently on 4.0, and is a Premier OEM customer.
