Overview

The Microsoft® Windows® Installer is an application installation and configuration service. Instmsi.exe is the redistributable package for installing or upgrading Windows Installer.

Windows Installer is a component of the Windows 2000 operating system and that simplifies the application installation process.

Windows Installer manages the installation and removal of applications by applying a set of centrally defined setup rules during the installation process. These setup rules define the installation and configuration of the installed application. In addition, you use this service to modify, repair, or remove an existing application. The Windows Installer technology consists of the Windows Installer service for the Windows operating systems and the package (.msi) file format used to hold information regarding the application setup and installations.

Windows Installer is not only an installation program; it is also an extensible software management system. Windows Installer manages the installation, addition, and deletion of software components, monitors file resiliency, and maintains basic disaster recovery by way of rollbacks. Additionally, Windows Installer supports installing and running software from multiple sources, and can be customized by developers that want to install custom applications.
