I understand the benefits of using/registering an Attended bot with the Orchestrator and from a developer and support point of view it is a must.
Although my question is would I be able to (allowed to) deploy and run my single Attended bot in Production without using (purchasing ) any Orchestrator License?
The anwser is yes.
You can have standalone installation (No studio) of the Robot and license it through Regutil (see bellow).
You would select only Robots from this wizard (or similar options on the latest one).
It is described within the “From command line” Section.
