Is that ISO viewer somehow called "Power2Go Essential"? Because I'm looking at it right now and I might be looking at the wrong thing...
"This is a component of CyberLink's Power2Go program, and what ISO Viewer does is, you can mount an ISO to a virtual drive(2 avaiable, I believe), and then that drive acts as a CD, so you can extract files this way, or play an ISO if the .iso is not compatible with Dolphin, like Septerra Core, for example."
So yes, it is. I have a download link for the free version
here, too.
