What is a .MSI file?

The file extension .MSI stands for a Windows Installer Package. This type of file is used by the Windows operating system to install new programs or updates. An MSI file includes all the necessary information that tells the computer how to install the program correctly. This information can include which files need to be installed and where they should be placed on your computer. MSI files are commonly used not only for installing new software from various developers but also for applying updates to the Windows operating system itself.

To open an MSI file, you can use the Microsoft Windows Installer, which is a part of the Windows operating system. This means you don't need to download or install any additional software if you are using a Windows computer. Simply double-clicking the MSI file should start the installation process.

Alternatively, you can use a program like 7-Zip to open an MSI file. 7-Zip is a free software that allows you to view and extract the contents of many types of archive files, including MSI files. This can be useful if you want to see the files contained within the MSI package without installing them. To use 7-Zip for this purpose, you would right-click the MSI file, choose 7-Zip from the context menu, and then select 'Open archive' or 'Extract files'.
