I downloaded and ran the installer from here
It completed without error, but launching onedrive for business still runs groove.exe (it should be onedrive.exe, it says so on the same site). Also, onedrive.exe cannot be found on C:\
Correction; onedrive.exe is on C:\, launches, and goes through the configuration process as described. However, GROOVE.EXE still launches in the background! Should this be happening? If I read it correctly, only onedrive.exe should launch.
