Hi Dewg,
We upgraded AEA console some 2-3 weeks ago, till now no abnormality is encountered, 100 out of 300 PCs are already on 1603.
Few Win 8/8.1 machines we have also were upgraded to 1603 smoothly. Screenshot is attached.
In my turn, I would also be grateful if someone help with question I raised here - http://forum.avast.com/index.php?topic=145975.0
Thank you
