I have Windows XP and found Free Software that I downloaded from the Internet on my Desktop. It downloaded but won't install. I than went on my Laptop and downloaded it from the same site and it installed right away and is up and running on my laptop. I have all the requirements on my Desktop that is required for this software so could there be a problem with the computer that a tech needs to look at. This is not the first software that I have tried to download that will not install.
