    This doesn’t work for me. When I get to step 5 and it looks different on my PC.
    I get a box that says “Select this object type”, From this location”, & “Enter the object name to select.”

    I figured Object type was maybe what I was looking for. So click it and uncheck every box except Users. I thought if I left Users as the only one checked then that would be the one that had permission. I hit okay and then I can’t hit okay again in the original box my only option is to cancel.

    All the other ways of changing it are greyed out and I have no choice.

      Don’t get confused. It was easy. Just revert all the changes what you did in this. You just needed to type the “users” in the “Enter the object name to select” field and then click on OK. The file owner will be changed. See the below-given screenshot.

    I now get an error saying “You require permission from Users to make change to this file”

      It seems like you have changed the owner to “users” successfully but did not grand its permissions to “full control”. To do that, we request you to please follow the step 7 from the above article. Watch this video tutorial to know more about it.
