You can also use msitools (https://live.gnome.org/msitools; right now they are not packaged for any distro, but will be in Fedora soon): ----- #! /bin/bash # extract-vsssdk-headers # Author: Paolo Bonzini <pbonz...@redhat.com> set -e if test $# = 0 || ! test -f "$1"; then echo 'Usage: extract-vsssdk-headers /path/to/setup.exe exit 1 fi # Extract .MSI file in the .exe, looking for the OLE compound # document signature.
