I ended up making a support ticket and received the following instructions, which worked for activating a new license.
To acquire the Attended license from Orchestrator, the download link and installation instructions for 18.4 can be found on page 2 of the attached document.
You must generate and upload a new license file to Orchestrator to see the license updates. For 18.4, please follow these steps to do so:
Then, please follow the steps to create and connect the robot in Orchestrator, then activate the robot.
- Creating/Managing Robots in Orchestrator: Managing Robots
- Connecting Robots to Orchestrator: Connecting Robots to Orchestrator
- Licensing a Robot: Licensing a Robot
If you prefer to use a standalone key for Attended, we can unlink it from Orchestrator, but it will become a node-locked Attended license.
