Ability to install additional software On request
Make a request to the office where thin clients bought - they will issue you an invoice for the installation of additional software, pay, receive.
Yep, shaz. Thin clients are loaded either from ROM (firmware) or over the network from an image on the server. Installing the software on the fly is not possible.

Download the required package from the network, upload it to the thin client and install it? Here you can start with apt-get. And then - already through apt-get to put everything you need.
