About Windows Installer Packages (.msi)

AdminStudio 2023 | 25.0 | Application Manager

Application Manager supports the import of Windows Installer packages (.msi). A Windows Installer package contains all of the information that the Windows Installer requires to install or uninstall an application or product and to run the setup user interface. The .msi file can also contain one or more transform files (.mst) and one or more patches (.msp).

A Windows Installer package is organized around the concepts of components and features:

•

A feature is a part of the application’s total functionality that a user may decide to install independently.

•

A component is a piece of the application or product to be installed.

The Windows Installer always installs or removes a component from a user’s computer as a coherent piece. Components are usually hidden from the user. When a user selects a feature for installation, the installer determines which components must be installed to provide that feature.
