Uncommon UI layout for Windows installer for Techsmith Snagit

Question

Does anyone know which windows installer/packager TechSmith Snagit v12 uses? The UI layout of the installer doesn\'t look like standard Windows Installer.

Answer 1

As Bogdan already has explained, this is a small application that handles the GUI part of an installation suite (several installations in sequence as a bundle). MSI has a feature to allow an external GUI via its MsiSetExternalUI function. This way you can handle messages returned from the Windows Installer engine yourself inside your own GUI - this includes the progress bar. Here is a technical example.
