One of my favorite little helpers:
Universal Extractor is a program doing exactly what it says: extract files from any type of archive, whether it's a simple ZIP file, an installation program, or even a Windows Installer (.msi) package.
... and indeed anything Installshield (see list below).

Universal Extractor is freeware and portable.
It's a brilliant utility to extract drivers or installers to make applications 'portable' and as they claim, it really works for pretty much any form of archive.
