So Disappointed with my M6800. Fingerprint not working

I bought a new Dell Workstation M8600 with very high specs that costed me around 7000USD. When I received my laptop it shipped with app called DDP Console. I have tried to set my Fingerprint but the sensor does not recognize that I am placing my finger. I went to Dell support website and download both :-

1. Dell ControlVault Driver

2. Dell ControlVault Firmware Update

when I run ushupgrade.exe I get message says"The Credential Management is initialized. Please enter the ControlVault Admin Password to update the ControlVault Firmware." I have no idea what is my CV Admin Password. I have not set any password in bios at all. and if I use my windows user password it start displaying

----------------------------------------------------------------------------
