Asus Fn keys not working after reformatting

Hi,

So I just had my computer reformatted and now my Fn keys do not work, the F1-12 keys combined with Fn (eVolume and such). I was looking around and found the conclusion that I do not have the essential preinstalled Asus bundle of software; I found it here.

I checked the website to download the software.

However, I am not sure where to look and what to download! Am I even going to the correct page to do the download? I also found that this fixes it too:

But when I type in the command, the furthest I get is to the C:\ Program Files (x86). After that, I do not have the ASUS folder. If someone could please help me, I would be very grateful!

Links to other pages for the downloads would be appreciated as well.
