Hey [NAME]  Prior to MS creating Windows Hello Dell used the Dell Data Security Tools product to enable fingerprint login\functionality.  That might be an option we can use to get fingerprint logon working on your M6700. Have you done a complete uninstall of anything control vault yet?  I was thinking maybe removing any controlvault software, deleting the device in device manager, and then downloading the Dell Control Vault Firmware and Driver from your devices Drivers & Download page.  Once those are downloaded execute the firmware first and let that run.  Once that is done install the driver package.  Reboot and see if that changes anything in the hello setup screen. Would you mind Private Messaging me your devices service tag?  I can use that to see if I can find a matching system and attempt to reproduce.
I have an older Precision M6700 mobile workstation that has been updated from Win 7 Pro to Win 10.  The system still has the old Dell Data Protection Access software and I would like to uninstall it and clean it out.  However, it does not exist in the Programs and Features control panel, and there are no uninstallers in the Access program folders. When I try to run the Access program, I get an error "Your USH firmware is not up to date".  The only installer for Access is from Windows 7 which won't run on Windows 10. I would like to clean this off my system, but am stuck and don't know what else to do.  Any suggestions? Thanks!   P.S. The DataSecurityUninstaller.exe program can't find anything to uninstall.
