To share a single V6 license between multiple computers, you need to use the Cloud Zoo with your license in the Personal list.
This requires an initial Internet connection to create a license “lease” on that computer. Typically, the least is 2 weeks. Rhino will run for two weeks on that computer without any Internet connection.
When Rhino starts, if there is an Internet connection and your lease is 10% or more depleted, Rhino contacts the license servers and refreshes your off-line lease to 2 weeks again. If there is no Internet connection, the license update fails silently and Rhino starts.
When your off-line lease gets under two days, Rhino will begin warning you that your lease is going to run out and will get more and more insistent as that deadline gets closer.
You can always check your current off-line lease in Options > Licenses. It will tell you the date and time Rhino will stop. If everything is working normally, it will be 2 weeks out. If it’s less than that, see what you can do about getting connected.
Your Rhino account also has a login associated with it, much like Google or any other tool that needs to be refreshed occasionally. I think the Rhino account login (gives you access to the discussion forum and Cloud Zoo tools), is about 90 days.
If you know you will be totally off-line for more than two weeks, you’ll need to remove the license from your Personal Cloud Zoo licenses, and deploy it stand-alone on one computer. Then no Internet access is needed at all, but you will be limited to Rhino on one single computer.
