cannot install the ISO

[Federico Bruni]

I've created my first image with live-build and I can run it as live. 
However, nothing happens when I click on Install or Graphical install 
in the boot menu.
What can be wrong?

Do you suggest adding the package debian-installer-launcher?
I'm running it with:
kvm -cdrom binary.hybrid.iso

You can find the first stub of my project here:

Thanks in advance
