What is Windows Installer

InstallerExpert created the topic: What is Windows Installer
The Windows Installer (previously known as Microsoft Installer[1]) is an engine for the installation, maintenance, and removal of software on modern Microsoft Windows systems. The installation information, and often the files themselves, are packaged in installation packages, loosely relational databases structured as OLE Structured Storage Files and commonly known as “MSI files”, from their default file extension. Windows Installer contains significant changes from its predecessor, Setup API. New features include a GUI framework and automatic generation of the uninstallation sequence. Windows Installer is positioned as an alternative to stand-alone executable installer frameworks such as older versions of InstallShield and Wise (later versions of both products are based on Windows Installer) and NSIS.

Microsoft encourages third parties to use Windows Installer as the basis for installation frameworks, so that they synchronize correctly with other installers and keep the internal database of installed products consistent. Important features such as rollback and versioning depend on a consistent internal database for reliable operation.
