Wd backup only shows dropbox

I have just purchased wd my cloud I have downloaded the back up software, when it scans for devises it only finds drop box wd acess cant find the devise either,yet it is on my network

What specific My Cloud device did you buy? What is the name of the software you downloaded? Have you properly setup the My Cloud and can you see it with the computer? The single bay, single drive My Cloud (the general subject of the My Cloud subforum) supports using WD SmartWare for Windows. For Mac one uses Time Machine.
