HI @767737Jockey,
Try to delete the %localappdata%\Temp\Navigraph folder completely, it could be that there is a permission problem with a file within it. Hub will automatically recreate the folder. Also for extra caution, make sure that AS is not running when you are updating the cycle.
Please tell us how it goes. In case it fails again I have turned on extended logging for your account so that we might see from our side what is going wrong.
Kind regards,
Markus
