System extension load
Check to see if the SFC Viewer extension is present in Maintenance Extension section of config wizard.
Also I see that you are using 6.0 version. If you have opened configwizard for troubleshooting, its ok but be aware that You shouldnt do any action using config wizard in 6.0. Let System Installer handle the installation and configuration of 800xA System. Else, you will face issues during update of the system in future.
