Instyler Ex-it! for Windows Installer is a powerful helper application to create single executable files from your Windows Installer (msi, msp, msm) files. You can create an executable package file that performs a version checking on the user's Windows Installer Service. Any prompts and language texts on the wizard pages can be adapted, a silent mode is also available. Plus: the new integrated block-wise compression algorhythm creates smaller output executables in most cases because of msi database headers that can be compressed very good. Test it.
