As I mentioned, when I clicked on Acrobat DC Classic 2015 a screen pops up for a second and then disappears, or nothing happens at all (all of my other sites are working). I just uninstalled Acrobat DC Classic 2015 as well as Adobe Creative Cloud, cleared browsing data, reinstalled Acrobat DC Classic 2015 (and the install seemed to accept my license code) and go through the installation, and still when I click on it a screen pops up for a split second and then disapppears. I am working off of this page when trying to install Acrobat DC Classic 2015. I am at a loss as to what to do, and I would like to avoid having to go back to Dell to try to get their help again in installing this on the new computer from the old computer (I logged off from my Adobe Account on the old computer and am still logged off--I just checked). I'd really appreciate help in getting this valid product installed on my computer.
