Deactivate a single computer license

How do I deactivate a single computer license before it’s up for renewal? Change the computer name or ???


Do nothing. It will stop working.

Or login to duplicacy account and change the hostname next to the license, then it will stop working immediately.

What’s the goal?

That’s what I thought, but maybe I’m on the wrong page. I’m on logged in on, but I can’t see a way to change those host names; I can highlight the text, but it’s not editable.
NEVERMIND: They expired yesterday, so I just renewed what I need to keep–then those were editable.
