Could you clarify a few things about your current licenses? Maybe a quick screenshot from the License page in Orchestrator.
You have also mentioned that you have previously used the Trial version. Well, there should be no issue using the same machine with your purchased license. You will lose no settings, as the license activation doesn’t delete any files
Now, it is a bit unclear to me how your setup looks like. In basic terms, node locked license can be activated on any machine using the “Activate Stand-Alone License” button.
I believe you can use either the email that was used to purchase the license on all machines, but it might not be mandatory.
If you happen to have your trial code still active on the machine, you might need to de-register the machine by using a command line:
For the named user licenses, those are managed by Orchestrator and are related to your Active Directory settings. This means that all you have to do to license your Studio is to connect your machine to Orchestrator (via the Robot agent). If the licenses are properly upload to Orchestrator and the robot is set up for the named user, then Studio will be activated from Orchestrator
Now, you’ve mentioned that the Orchestrator setting does not display those licenses and a screenshot would help here to understand the situation (please blur out any sensitive information).
You can also contact our licensing support directly - they will have more insight into your particular case
