MSI
MSI (Microsoft Installer) is a Windows-based installation and configuration service framework used for packaging, distributing, and managing software applications. It provides a standardized way to install, update, repair, and uninstall programs on Windows operating systems, ensuring consistency and reliability across deployments. MSI packages contain databases with information about the application's files, registry entries, and installation logic.
Developers should learn MSI when creating Windows desktop applications that require professional installation processes, especially for enterprise or commercial software distribution. It is essential for ensuring clean installations, handling dependencies, supporting silent/unattended deployments, and enabling features like rollback and repair. Use cases include deploying business applications, system utilities, or any software that needs to be managed via Windows' built-in tools like Add/Remove Programs.
