Cannot install Norton Family

I am having trouble installing Norton Family on a second device.

I am able to log into the website and download NF_Installer.exe version 5.0.0.64

I open the installer file and get a popup titled "Norton Download Manager" while a progress bar for Norton Family chugs along to 100%. 

On completion "User Account Control" pops up requesting permission for Norton Family to make changes to my computer. I choose Yes.

This is where I run into trouble. The "Norton Download Manager" shows up again prompting me to (1) Cancel Install, or (2) Retry. 

I have attempted to shut down, uninstall, reinstall, etc with no success. I found a few threads where others seemed to have similar issues, but there was no resolution posted.
