As we first had the Trial version installed I used the Regutil tool to update the licenses (offline mode).
I first did this for the Unattended Robot License and then for the Studio License.
When I afterwards executed the “Regutil get-info” I get the following output.
After development completed remove that licence and install unattended BOT licence. And also one more thing as you said you don’t have Orchestrator right. Then how you will trigger this unattended BOT and to trigger Unattended BOT we need Orchestrator and it’s mandatory.
