New Passport will not set up

Running Windows 10 on a desktop PC. I bought a new My Passport to replace an old Passport Ultra. Disconnected the old drive from my PC and attached new MyPassport, which is recognised in Explorer and I can add/delete files etc, so basic drive seems OK.

Downloaded Discovery, but it will not recognise USB device nor will it install Backup or Utilities etc. My existing Backup etc software keeps looking for the Ultra Drive but does not recognise the new drive.

How can I set up WD to use the new drive?
