MSI is an installer package file format used by Windows. Its name comes from the program’s original title, Microsoft Installer, which has since changed to Windows Installer. MSI files are used for installation, storage, and removal of programs. The files are contained in a package, which is used with the program’s client-side installer service, an .EXE file, to open and install the program.
