What does MSI mean?

MSI is short for "Microsoft" and is an installation package in Microsoft format. Generally, it is the installation software of the program. You can run the installation directly under XP, and you need an InstMsi program to run Msi files under 98.

The purpose of Windows Installer includes: managing the installation of software, managing the addition and deletion of software components, monitoring the recovery of files, and using rollback technology to maintain basic disaster recovery.

Extended data:

Windows Installer technology is two parts that work together: client installer service (Msiexec.exe) and Microsoft software installation (MSI) package file.

Msiexec.exe program is a component of Windows Installer. When the msi file is double-clicked and Msiexec.exe is called by the installer, it will use Msi.dll to read the package file (. MSI), application conversion file (. Mst) and merge the command line options provided by the installer.

Windows Installer performs all installation-related tasks, including copying files to the hard disk, modifying the registry, creating desktop shortcuts, and displaying prompt dialog boxes when users are required to enter installation preferences. In this way, a program is installed on your computer.
