In order to successfully use AcritoxInstaller, you need to have installed the following packages: expect, lvm2, dmsetup, cryptsetup, parted, dmraid (>= 1.0.0), initramfs-tools, os-prober

Usually you have them preinstalled because the debian-package of AcritoxInstaller depends on those packages.

You can find a list of changes at http://home.acritox.de/projects/acritoxinstaller.
