Patchs for upgrate clients from 14.x to 14.2 hxxps://support.symantec.com/en_US/article.INFO4393.html
Just a heads up: 14 MP2 under 16299.15 isn't able to automatically takeover/disable Defender Firewall. It must be done manually to avoid having two firewalls at the same time.
Anybody know why they're still maintaining 12.1.x? Is there a significant difference between 12.1.x and 14.x?
Version 12 is not fully compatible with windows 10. Windows 10 creators update removes version 12 as incompatible.
