The QuickZone demo will provide you with access to all input and output screens for the example network delivered with the actual QuickZone software. You will be able to change input values to get a feel for the interface, but none of the changes will be reflected in the results. You can also review the QuickZone Editor by running the included QZEd.exe file, but you will not be able to open any created network in this demostration version of QuickZone.
