before asking i have tried over & over to find the .ino file in the download, i have followed the directions step by step & when attempt to “Open the firmware folder and select the current Marlin.ino file” there is no .ino file in there just whats in the images bellow.
if i open the arduino file its empty.
i have flashed a fair amount of boards & haven’t came across this problem

Open the Marlin folder.
Oh, wait. In file explorer, click on view at the top, then check “file name extensions”. Why msft makes extensions hidden by default is a freaking mystery.
I did open that folder, that’s the 2nd image i posted. there is an Arduino file in there but its not an .ino file & when i open it there is nothing in it ,no configuration.h ,nothing.
The ino file is right there. But the real problem you are having is that you are looking inside of a zip file. You can tell by the path in the address bar and the fact that your image called screenshot 3 shows the compression ratios next to each file. Just extract/copy the files out of the zip file and it should work fine. (I hope). The ino file I think is the one in the picture that says it’s an ardunio file.
Microsoft doesn’t let you open many programs with files in a zip file. I am sure that arduino is opening the marlin.ino file and not finding any of the other code files because they are hidden in a zip file.
