How to Install Iris in Silent Mode (No GUI) onto PC's

Basically, in the psappdeploy kit, the software extracts with “-s” silent switch (and variations tested as well) but once the package has extracted it crashes with a 1001 error.

if I run it with no switches (parameters) it extracts and presents me with the installation options gui

Ideally, we want to do a full unattended / silent installation
