Can't download Norton Family on Windows 10

My son's laptop got upgraded to Windows 10 automatically and Norton Family started to behaved erratically, so I decided to uninstall/install, but I can't install since Norton Download Manager cannot download NF. The NF_Installer 1MB installer gets downloaded, it starts, but after a couple of seconds it stops with the message "Click Retry to continue your install" and it gives the options to "Cancel Install" or "Retry". 

Obviously I hit try and the same thing happens over and over.

I downloaded NF by signing in to the NF website and clicking on the "Download Norton Family Now" section/button, which downloads the NF_Installer.exe file.

I've also tried deleting C:\Users\Public\Downloads\Norton directory and the C:<my user>\AppData\Local\Temp directories without success

How do I fix this and get NF installed again ?
