I am sure it’s user error. I will have to try a different laptop.
The strange thing is when I save the other firmware updates to my thumb drive they do save as .2gig files. For whatever reason the latest update saves as a chrome.htm.
The laptop that wouldn’t save the file correctly was a Dell running Windows 10 Home, Version 1607. I tried using Internet Explorer 11 and Google Chrome.
The second laptop, which downloaded the file correctly, was a very old Gateway running Ubuntu.
Thanks again for the help. The update was successful.
