Why can't I install Kies on PC?

[AC Question]

Hi,

I'm trying to install Kies on my laptop but it keeps coming up with 'You are not connected to the internet. Installation cannot proceed. Please check the Internet connection and try again.' I'm definitely connected so not sure what's going on.

I've been searching online for ideas but not getting anywhere, but am also getting confused with what I'm finding as I'm not very good with troubleshooting computers etc. If anyone could help me out with what to do, thoroughly dumbed-down, that would be great!

Cheers
