When installing Marketing in a production organization, it can take up to 6 hours. In our case it took 5 hours to complete the installation. For the first 3 hours the progress bar was sitting at 28% completed and the message was misleading as System Administrators might think something wrong is going since it says it will take approximately 10 mins!!

Please consider updating the message and provide a more realistic and accurate estimated time to completion. Ideally this wizard should update users about the steps that are being performed as part of the installation and the status.
