What is a MSI file?

A .MSI file is a Microsoft Windows Installer file.

These files are installer files for the Microsoft Windows operating system. When a user installs an application onto their computer, the software uses a Windows Installer package to install the software onto their hard drive.

The MSI file tells the computer which files to install and where to install the files on the user's system. The MSI file format is structured like a miniature database that is laid out in a structured storage file.

In addition to performing Microsoft software installs, MSI files can also perform Windows updates and third-party software installations.
