Norton Management site for downloading current product, Norton 360

I am viewing a video describing how to download a copy of a current product, Norton 360 version 20, in my case; but I want to be able to download the MOST UP-TO-DATE installer, and I do NOT want to use Norton Download Manager ---- I just want the installer so I can install directly over the version on one of the machines, being version 19.

 

The site describing what I am finding is https://support.norton.com/sp/en/us/norton-billing/current/solutions/kb20090708112600EN_EndUserProfile_en_us

 

I already have and used ESD-20-2or3...something-EN.EXE, and used it on one machine and it worked well, but it is about a 5 or 6 month old installer.  I hope to be able to download the most current installer and use it instead of the ESD-20-2or3...something form. 

 

Can someone remind me the direct download link for Norton 360 version 20 installer for the most recent installer?
