What is an MSI file?

MSI files mostly belong to Windows Installer by Microsoft. An MSI file is an installer package for Windows operating system. It contains information such as registry values, media assets, installation rules, and compiled code which make up a Windows program. An MSI file is similar to a Windows executable (EXE). However, unlike an EXE file, it is difficult to have an MSI file install other executables (e.g. .NET framework) during an installation. MSI format also gives a developer limited control over the configuration for installing a program. msiexec.exe (The Windows Installer Engine) runs an MSI package when a user double-clicks the package.

How do you open MSI files?

Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert.

MSI file format:

The file format determines how the data is stored in the file. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. So a detailed analysis of a file is vital in order to determine the format and the associated program. Below you will find our evaluation of the MSI files:
