Opening MSI files

Did your computer fail to open a MSI file? We explain what MSI files are and recommend software that we know can open or convert your MSI files.

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.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
