What is an MSI file?
MSI files or Microsoft Installer files represent Windows installer package files that store installation information. Installer packages are data collection sets (relational databases) into formally arranged data tables. MSI files are used by some versions of Windows during installing updates from Windows Update and using third-party installation tools. The MSI file contains all the information necessary to install the software, including the files that need to be installed and where those files need to be installed on your computer.

Setup MSI
A setup MSI is a setup.exe file that acts as a bootstrapper because it contains an MSI instead of individual files. However, some setup.exe acts as a non-MSI installer to extract the installation resources and manage their installation directly. In this case, the setup.exe will call Windows Installer to install the MSI.
Many organizations offer IT developers MSI versions so they can customize the software in their environments. For example:
