Use the Custom Actions and Sequences view to specify where you want to place custom actions and dialogs in your installation. You can place a custom action into one or more of the following sequences:

- Installation Sequence—The sequence that executes when the setup runs in the default installation mode, such as when the user double-clicks a new .msi file or Setup.exe.
- Advertisement Sequence—The sequence that executes when the user launches the setup with the `/j` command-line option.
- Administration Sequence—The sequence that executes when the user launches the setup with the `/a` command-line option.

The Custom Actions and Sequences view supports drag-and-drop editing and copying:

- To sequence a new custom action, drag it from the Custom Actions explorer to the appropriate location in a sequence under the Sequences explorer.
- To move a dialog, standard action, or custom action to a different point in a sequence (or from one sequence to another), drag it from the old location to the new location.
- To copy a custom action from one sequence to another, press and hold CTRL while dragging the custom action from one sequence to another sequence.
