All I remember from January was I couldn't find it in my "downloads" folder but did find it in my network downloads, used my Ford Pass info & it worked for me....that was a couple months ago though.....I wish I had a better answer....I have windows 10 pro & FDRS version 38.5.7
Mine is a 21 XLT PB.
I use the tender no matter what since I don't cycle the ACC, I just leave it turned on throughout, unless I have to use the USB.
I actually had 4 SW updates, took a little under 2hrs.
I'm no pro but as far as I know you or a dealer have to download & install these updates.
I've done my truck twice in 3yrs. The first time was 15hrs over 2 days & this last one (I only had 4) took me a couple hrs.
It was well worth the cost of the equipment to NOT have to take it to a dealer. On...
