Some screens only make sense when corresponding actions are used later on in the installer or uninstaller. For example, the "Services" screen will only be displayed at runtime if there are "Install a service" actions present on a subsequent screen. If such a dependency is not fulfilled after adding a screen, a corresponding notification is displayed.
Screens have actions attached. To quickly jump to the attached actions of the selected screen in the
actions configuration, you can use the
[Go To Action] tool bar button.
If you select a single screen in the list of screens, you can edit its properties on the right side, if you select multiple screens, you can copy them to the clipboard or delete them with a single action. If your selection is a single contiguous interval, you can move the entire block up or down in the list.
