The N360 apparently survived the upgrade done Saturday Mar 20. On reboot today there was no Console launcher in the System Tray and desktop Icon did nothing. A window popped up saying that error 8504,104 had been detected amd pointed me to a help page that was of no use. The release level reported in the pop up was 21.2.0.38. I unistalled N360 choosing to save my settings.
The release DVD I have will not re-install due to compatibility problem despite setting the compatibility property in the setup utility.
How should I proceed.? I am using Win Defender for now.
