Considering the circumstances of its lack of availability, the link was posted at a forum and a request made in that forum for a link. To be honest, it appears that all development has been abandoned and I haven't heard of any protest to the program being shared since it was free, to begin with. On the other hand, I did come across a youtube tutorial post integrating DAZStudio panorama render for creating HDRI in Photoshop. Again, it's basically taking LDR Images, 1-stop over/underexposures, and converting to HDR. A trick to use an environmental HDR for both background and lighting to render a scene much more quickly. I was impressed. I wish Poser had a 360 panorama camera for something like that.
