I am being presented with this lovely problem...
“The sonos controller is currently running from another user on your computer. Please quit the Sonos controller from the other account before installing”.
Problem is that there is no other user accounts on this device, no separate Sonos application running in the background, device has been rebooted and I’m still being presented with the error.
I’ve even reset the controller which made no difference.
To make matters worse, if I try to do the update on my mobile device, it says there was a problem checking for updates and to try again.
It would be very helpful if the error messages were more meaningful and accurate.
