WD Backup won't install

My Passport Ultra, Windows 10 Home.
WD Backup program will not install. The drive shows up in my E drive, and I can drag & drop or copy and paste, but I won’t have the ability to backup automatically.
More info: When I try to install WD Backup, when it is about 3/4 done (blue indicator), a window comes up that says Setup your first backup. I click on Back up Files, and it goes to Discovering Devices, and then it says " No backup targets found", and a button that says Rescan. I’ve done that about 20 times, and it finds nothing. WD Utilities and WD Security installed without a hitch.
