Mary,
you may have a corrupted download, download again and if still can't install then it most likely isn't the download, Do a scandisk, see if it finds any problems. Hope you get it installed, hope you don't find more problems with hal as I have. I hope the makers of HAl at Zabaware are reading these posts, maybe they will address some of these problems we are posting. What ever happened to customer service ? Well, I am not yet a paying customer, still using the 15 day trial full version (approx. 90mb) and I can't get it to work very well either, the speech recog feature is a nightmare, with a absolutely silent room it is hearing voices that seem to be non-stop and of course it is replying to those silent voices. and still have the same problems I had with the basic free program. Until I get hal to work smoothly with the free one I won't be buying the commercial one. Gary
