Query: I want to work this puzzle, but

I had purchased this puzzle before, for my other computer, an HP. I tried to download it onto the Dell and needed Quicktime. Then, onscreen, it claimed that my Windows wasn't the correct version. As often as I had tried, nothing worked. I even read the booklet that came with the CD which gave a tech support web site. I wrote them and never heard back from them. This is a huge disappointment.
