Well I had the same issue from 2 days on my Inspiron 3511 but I have figured out the solution what you have to do is  1. Open Control Panel And uninstall dell Fusion/ Fusion Service  2. Visit dell support page and enter you system model or Scan With Dell support assist and download the latest version of Dell Fusion service once you have successfully installed the fusion My Dell Application problem should be solved  or install from this link [URL] Please reply if this method worked
