Hello,
Since the last ARC update I've started seeing a new issue: ARC shows a popup error and hangs during shutdown, preventing the robot from completing its shutdown sequence. I do not allow Windows 11 OS updates on the robot's mini computer, so this started after the ARC update.
A few details about my setup and workflow:
- Hardware and connection model: I have a mini PC mounted on the robot that runs ARC and is connected to three EZ-B v4 controllers via USB. The sensors/actuators (including ADC inputs) are connected through the EZ-Bs and are visible to ARC.
- Remote access: I do not attach a monitor to the mini PC. I control and view it remotely over TightVNC. Most animations and behaviors are autonomous.
- Shutdown automation (ARC scripting): I have an ARC script that watches a momentary button on the robot. When I push that button during shutdown, one of the EZ-B v4 ADC ports (as seen by ARC) detects the expected voltage change. That triggers a PC shutdown script, and after some additional automation the whole robot has powered down cleanly for a long time.
- Problem behavior: After the PC shutdown script runs, ARC begins to shut down: my scripts close (it looks like ARC is turning off), and any running scripts stop. Just before ARC closes, it hangs and a popup appears (screenshot below). The popup claims both seats have been assigned and gives choices. I then must click the "X" in the popup to close it, after which ARC exits and the robot finishes shutting down.
- Account/seat observation: When I check my Synthiam account, the robot's mini PC is listed as one of the seats. It’s odd that ARC starts and runs correctly on the mini PC, but then hangs at shutdown with a message saying my two seats are full.
- Attempts so far: I tried removing the robot’s mini PC from my account seats and then re-enabled it as a seat when ARC starts on the mini PC, but the error still occurs and ARC hangs at shutdown.

How can I get this to stop and allow ARC to shut down properly? Any help is appreciated. Thank you.
Hmmm, okay, I understand. We had an update to the subscription panel in the user account section of the website that I think will be useful. I had it pushed now. There is a new section that shows the activity log, so you can see when seats are modified. You can compare that against what you're doing to see what's up.
What you're suggesting is totally accurate. I do it all the time because we run school classes with a limited seat count (I only have 50) and always delete/re-add as needed. This new activity log should help diagnose what's going on. Let me know if it's helpful
