Note: this advanced option screen is reachable by selecting the "Executable" step and choosing "Menu name" from the [Advanced options] popup menu or by clicking directly on the index.
For GUI launchers, you can select the Execute downloaded updater installers at startup check box in this step. When this GUI installer is started and a downloaded update installer has been scheduled for installation, the update installer will be executed.
By default, the execution mode of the update installer is set to "Unattended mode with progress dialog", but in this step you can change it to a different execution mode. If "Unattended mode with progress dialog" is selected, you can customize the message in the progress window.
