You must be adivised that although this product works exactly as advertised (I had no problems installing, although they could be a bit more clear in their instructions) I found the hard way after wasting a whole day screwing with it that there is a fundamental conflict with OS 10.3.X. I only found it out after demanding a free tech support phone call (and raising hell to get it) that THIS IS A KNOWN ISSUE at Corel, and they have no plans to fix it. The trouble is that you must restart the machine after processing an image in order to process another one. Yes, it works perfect on the first image per restart, but on the second image you try to process, you can attemp to apply the results to the host (Photoshop Elements 2) and nothing happens. All your work on masking the image is just gone. Restart the machine, try it again, and it works fine—for one image only. So, I am ambivalent; it works great if you don’t mind rebooting per image
