I had similar problem downloading the smartsource.mediamanager, I was using FireFox to download it. I had to change the brouser to use Internet Explorer, and it downloads now. Hope this helps.:emotion-1: Dell user.
Changed my hard drive to a SSD drive on my Dell XPS 15 (<ADMIN NOTE: Service tag removed per privacy policy>) and installed Windows 8.1 (originally came with Win 7).  Would like to watch movies like before the change but can not download PowerDVD from Dell My Dell Download website. Smart Source Media Manager Application downloads but gives me an error (shown below). How can I fix this error so I can reinstall Power DVD to my system?
