Cannot Reinstall Norton Safety Minder

I had to uninstall Norton Safety Minder because it kept turning itself off on my son's account.  I am now trying to reinstall it and I get this message:

This version of Safety Minder requires Norton Online Framework to be installed first.

 

I need to get Safety Mnder up and running ASAP and would appreciate it if you could let me know what to do to fix this problem.
