In Qubes, the Templates are where software is installed. If you install
software in an appVM, it will go away when you shutdown the appVM. This is to
implement a separation of software and data, and is one of the foundations of
Qubes.
If you want software available in a template based appVM, you need to install
it in the template. You can install uncertain software in an appVM for
evaluation and not worry if it doesn't work, as it will go away when you
poweroff the appVM...but then you need to install that same software in the
Template in order to make it available in the appVM.
