I have a Dell XPS 13 9360. Dell Update came installed on it, but after several months it didn't show any new updates. So I checked Dell's XPS 9360 support page, and found that several updates were available—including a new version of Dell Update.
So I uninstalled DU from my machine (via "Programs and Features"), rebooted my PC, downloaded the new DU installer, turned off Protected Folders (I don't have Windows User Account Control turned on), and ran the DU installer as an administrator.
The install said it was successful. However, the only file in its folder (C:\Program Files\Dell\Update) is Readme.txt (which itself has no useful details about the install). When I try to run DU from the Start Menu shortcut, Windows says the file doesn't exist.
