Thank you for posting your question on our forum.
Yes, you can install Pragma FortressSSH Client Suite software on the CLI ST 5560 and the HP T5565 Thin Clients/Terminals, but only on the version running Windows XPe (e for embedded) operating system. Our FortressSSH Client Suite software is NOT designed to work on other operating systems such as Windows CE 6 or Linux. Hope this helps.
