In my case, when it asked to update it, it asks admin permission and when I clicked "show details" it showed that it was trying to install something called "My Dell Fusion Service". After finding this is needed for My Dell, I manually updated it from the Dell website and now My Dell works (stops trying to endlessly update).
I use MY DELL to update my Inspiron, cleaning etc. A few days ago when I wanted to use MY DELL I got a message that I should update it. I follow all the messages on the screen and at the end I get an error that tells me that It is not possible to update it and to check my internet connection. My connection is fine and the problem is that I cannot use the previous version of MY DELL because the update message always appears. I have removed the antivirus.
MY DELL won't update
