MST File Viewer

The MST File Viewer enables you to view the files created with the Custom Installation Wizard. These files are not viewable simply by opening them in Notepad. They're essentially modified MSI files that are used to control the installation of Office. The MST File Viewer converts the binary file to a text file and opens it in Notepad, which enables you to review the installation details. You cannot change the installation details from this file.
