Hi @mcdrake, thanks for letting us know. I will create an incident report that you have reported a conflict between the Logitech X52 Software and latest (v2.11) edition of the Tobii Core Software.
I would recommend posting this as well on Logitech support forum in case they have already a solution available.
In the meantime, it would be helpful if you could describe in a little more detail what you meant by the tracker not working.. I assume you could still launch calibration from the system tray or did the LED lights stop entirely?
Which games was the setup tested in? Windows 10 Version would also be good know.
Hopefully this can be resolved in a timely manner. Thanks.
