JGS524PE firmware update

I have a JGS524PE switch as my main switch of the router. Other switches and POE switches attached downstream to run other computers, printers, cameras, POE switches, etc. I am trying to set up the fastest connection I can to the front office switch which has the NVR attached, then give priority to ports on other switches back to the NVR. 

I see there is a firmware update to the JGS524 that I have been trying to apply. I can get into the web interface on the switch, point to the update .bin file on my desktop, but when I tell it to apply it quickly drops back to login screen on the switch. When I check, the firmware is not updated. This happens on multiple computers  and I have turned off Norton protection and still no-go. The Netgear utilities give me all sorts of troubles and act like they are out of date/obsolete. 

Can anyone make sense of this/ The process should be straightforward and I always shudder when I sit down to get into these Netgear devices. FWIW, I am on a Netgear Orbi mesh router with 4 satellites around the property.

Thanks in advance for any advice.
