Haven't updated to 2.2 again, staying with 2.14 for now and it works, but curiously it no longer shows Software Updater v 2.2 as available update.

Thanks Steve I saw your earlier post saying to restore from a backup. That's somewhat ineffective when as soon as you update iTunes to 12.3 or QuickTime, they will both overwrite your old restored...

ASU 2.2 is unable to find the server. checked hosts file & added exclusions to AV and firewall, still no go. Just spouting on whether Apple is worse or better at software is not at all helpful....
