Norton 360 V3 Won’t Install

Hi!
I am trying to install Norton 360 V3 and it keeps coming up with an error.
Does anyone know how to resolve this problem?
The error message says:

” A problem has occurred that needs your attention:
The install file cannot be properly validated. Please try again. If you continue to receive this error message, you should run a Windows Update and then try again.
