What is a MSI file?

Files that contain the .msi file extension store installer files for the Microsoft Windows operating system.

When a user installs a Microsoft application onto their computer, the software uses a Windows Installer package to install the software onto their hard drive. The MSI file is what tells the computer which files to install and where to install the files on the user's system.

The MSI file format is actually 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 be used to perform Windows updates and third-party software installations.

These apps are known to open certain types of MSI files. Remember, different programs may use MSI files for different purposes, so you may need to try out a few of them to be able to open your specific file.
