It didn't occur to me to unrar the .exe file - you live and learn.

I will now apply myself to your helpful solution, and promise to remember in the future.

Just follow these easy steps mentioned above then, to unlock drag and drop the img in [Only registered and activated users can see links. ] program icon.
To unlock JCV [Only registered and activated users can see links. ]
Easy for lazy people
