First download the driver from LG site, in there just choose the type of your phone and download the software that is needed. After downloading the above, I had a quite hard time to get this done, it had an alert that I need to download something else from the site microsoft... somekind of update for windows.
Tt seems that the original link that has been given to us, is not quite right.
Maybe it is because of my windows 8.1 It just gave me the link for
"Media Feature Pack for N and KN versions of Windows 8 "
