Hello Vladimir,
I am the creator and owner of this demo. Everything you need to run this demo is located in that demo location. After you've successfully set up the virtual machine on the demo page (located on the right of the demo page),
you'll be able to log into ThingWorx Composer and complete the demo, with all required configurations available, within the VM.
