THANK YOU SO MUCH! This fixed the issue for me.I deleted I post I made just a few minutes ago on this topic because I found my problem. But thought I would post what I was doing incorrectly in case others experience it. I use a Mac and I primarily use Safari as my browser. There is a setting in Safari that I have screen shot included below. This must be UNCHECKED otherwise safari unzips the file as part of the download which messes up the process. This is in the instructions on the ford website but I missed it the first time I downloaded the update. Figured other Mac users might miss it too.
