                                recommends that you use setupConsole.exe, which runs in the foreground when
                                you perform a silent installation. setup.exe runs in the background, giving you the
                                impression that the installation has terminated, and results in
                                additional installation attempts using the silent installation.
                                Multiple installations at the same time may corrupt the Windows
                                Registry and lead to a failure to restart the operating
                                system.
