Project:This information applies to the following project types:
Defining the sequences of an installation is an important part of developing an installer package. Sequences specify the order in which Windows Installer launches the standard and custom actions that control the installation process.
Project:In Basic MSI and Transform projects, sequences also specify the order in which the dialogs are displayed.
In InstallScript MSI projects, the user-interface dialogs are defined in the InstallScript code, and the InstallScript engine controls the user interface part of the installation.
The Custom Actions and Sequences view in InstallShield is where you define the sequences of your project. The Sequences explorer in this view lists all of the actions and dialogs in your project in chronological order, according to when they are launched during the applicable sequence. Each action and dialog is given a number in the sequence, and Windows Installer runs the sequence from the lowest number to the highest number.
Rather than having to manually provide a numeric value for every custom action and dialog that you add to your project, you can use the Custom Actions and Sequences view to insert actions or dialogs into a sequence or edit the sequence timeline. Refer to this section of the help for information about sequences.
Project:If you create a custom action or a custom dialog in a merge module, you need to first import that module into an installation project and then add it to a sequence through the Custom Actions and Sequences view.
