This view allows you to include existing installers in your package. These installers can be executed before, during or after your main installation.
Existing installers can be added in multiple ways, depending on the moment you want to execute them:
- Pre-install - frameworks and runtimes required by your package or application. They are installed by an EXE bootstrapper before your MSI is launched.
- Feature-based - additional packages which are handled as features in your installer. They are handled by the installation user interface and are not supported by silent installations.
- Chained - packages embedded in your MSI using native Windows Installer 4.5 support. Are ignores on machines with older Windows Installer versions.
- Post-install - feature-based prerequisites which are launched after your main installation. They are also handled by the installation user interface.
You can change when a prerequisite is executed by dragging it over the appropriate folder (Pre-install, Feature-based or Post-install).
Global prerequisites are handled by our EXE bootstrapper. This is why the corresponding option must be checked in the Configuration Tab page.
All setup files used by a prerequisite can be bundled with your package or placed online and accessed through an URL. During install, if the prerequisite is not found it will be automatically installed.
Adding predefined prerequisites
Select Packages tree item to display the Frameworks and Runtimes page. You can then check the prerequisites you want to include in your package.
In Frameworks and Runtimes page you can also configure global prerequisite options.
To make sure that the target machines can run your installation package, you can include Windows Installer as a prerequisite. Windows Installer predefined prerequisites use special setup file locations. When building your project, the prerequisite installation package is downloaded automatically. If the download fails or you cancel it, an error message will be displayed and the build process is aborted.
Adding bundled prerequisite software
Use the Insert key. You will be prompted to pick the prerequisite setup files. If you cancel the files dialog, an URL prerequisite will be created instead.toolbar button, “New Package Prerequisite” context menu item or
Adding downloadable prerequisite software
Use thetoolbar button or context menu item. This type of prerequisite is created with default settings, so you need to configure it manually.
Adding chained packages
Use thetoolbar button or context menu item. Chained packages are handled by the actual installation process and are launched when the progress bar is shown.
Chained packages require Windows Installer 4.5 or higher. For older Windows Installer versions they are ignored.
Specify which builds will contain a prerequisite or chained package
Use the “Builds...” context menu item. A dialog with all MSI builds will be displayed. This option is shown only if multiple builds were created in Media page.
Adding a prerequisite from repository
Use the “Add From Repository” context menu item. A submenu with all the available repository prerequisites will be displayed.
This option is shown only if there is at least one prerequisite in repository.
Exporting a prerequisite in repository
Select the prerequisite you want to export and use the “Move To Repository” context menu item.
You can read more about the prerequisites repository in this article.
Editing a prerequisite or chained package
When selecting a prerequisite or chained package, it's properties pane will be displayed. In this pane you can configure all available package settings.
Use the Delete key while a prerequisite or chained package is selected.toolbar button, the “Delete” context menu item or press the
Reordering prerequisites and chained packages
The order in which the prerequisites and chained packages are displayed is the order in which they will be installed on the target machine. The Shift + Up keys will move a package up. The context menu item or Shift + Down keys will move it down.context menu item or
