E7450 Fingerprint Reader Not working - Windows 8.1

It does not appear that the fingerprint reader on my Dell Latitude E7450 is working correctly after only 3 days of ownership.  When I try to Add Fingerprints under PC Settings > Accounts in Windows 8.1 it is not possible to register a fingerprint when asked.  The application just sits there waiting for my input indefinitely.  Of course, I am trying to place and swipe my finger(s) on the reader.  

The Laptop came installed with Windows 7.   I decided to update immediately to 8.1.  

Under the Device Manager I can see that there are drivers "correctly" installed for this device under both Biometric Device and ControlVault Device.  The drive is Control Vault with Fingerprint Swipe Sensor 6.1.76 from Broadcom.  

I have also tried downloading the firmware from Dell at the link below.   However when I try to install the firmware update via Windows I receive a message that two DLL cannot be found:  BIPDLL.DLL and CVUSRIFC.DLL.  The expected folder for these two files is Windows\system32.

I am out of ideas on how I can get this fingerprint reader to work.   Any help is appreciated.
