Nav 2013 R2 web server component install error

I’m trying to install web server component on my laptop (win 8.), and I’m getting an error saying that Windows Authentication should be enabled for IIS.

I have checked the Windows Authentication check box under IIS setup, but there is no key in the registry (\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\InetStp\Components ) and I cant get permission to add this key.

Any help is welcome
