Another "B" data point: After seeing your post, I tried an update of my 33521B from 5.02 to 5.03, using version 1.0.31.0 of the Firmware Update Utility (over LAN). Worked fine.

Sorry this does not help you, but might be of interest to "B" owners who see this thread.

Good luck.
TheSteve:
I have a B model running 5.03 as well, no issues.

I'd power cycle the 33522A - it probably never even started the update. The on screen message is generated by a firmware update command before any updating actually happens.
Zucca:
TheSteve gets a cold beer, he was right the unit recovered after a power cycle.

Current FW
5.02-1.19-2.00-58-00

Upgrade error via LAN with KS FW update utility:


With the old FW update utility (which worked until the 5.03FW, the above was always failing with the above error)


I get:


back to square one.

Keep you posted.


Zucca:
Official statement from KS customer support, I told them I will not try with a second PC.


--- Quote ---That's a good idea try with a difference pc, but unfortunately if that doesn't work , there is no other fix. You would have to send instrument in for repair to get it updated.

So KS officially does not know what the error "Object reference not set to an instance of an object" means.
