I can't use NIS or Live Update since Windows 10 Upgrade

Hi. Good Evening. First of All I'm not Tech Savvy. I "Can't buy a Clue". I have 2 Issues to seek help with Please. 1st  I can't get Norton's Live Update to { Finish Installing Updates } 3/5 tries It states call support .Error. And my 2nd Request is, I can't get Norton's ID Safe to Open. It just does nothing. Thank You.
