A few ideas that may work, may not.
#1. Enable TrustedInstaller ("Windows Modules Installer") in your Services.msc. If it's already enabled or set to Manual, try Starting it.
#2. Be sure you are running the setup as Admin. Right click on it and choose Run as Admin.
#3. See Lylou's answer about "Super Administrator" on the link provided above: http

(whether it works or not).
