Adobe Downlaod Assistant will not install on Windows 7

I tried to download trial Version of Premiere Elements 13 on my Dell XPS 8700 and when I run Adobe Download Assistant I receive the following message "The application could not be installed because the installer file is damaged. Try obtaining a new installer file from the application author." I tries the suggested solutions but cannot download the Premiere Elements 13 file. What do I need to do to install this program?

Previously I had downloaded and installed Premier Elements  9, which I own, on to this same computer and it would freeze at the New Project Screen, I was unable to add A project Name,  Save a destination or specify a Project Setting.  I removed the program through the Control Panel and deleted the two installations files premier Elements_9_LS15 ad LS15.7. Also I deleted the expanded installation files from my App Data folder.  From the Start menu searched for AdobeDownloadAssistant and nothing was found. I am the signed in as the computer Administrator.
