M6800 How to install fingerprint reader ??

Hy,

my system details are:

Dell Precision M6800 + Windows 7 Pro X64

I had a painful and finally successful installation  of the fingerprint reader and controlvault about one year ago, using the following in this order:

1. Dell Data Protection | Security Tools-1.6.1.1055
2. Dell ControlVault Driver_94KTC _A18_64b_ZPE
3. Dell ControlVault Firmware_WJ0XJ_A38_ZPE

Now I had to reinstall my system and I tried to use the updated drivers:

• Dell Data Protection| Security Tools 1.10.1.16
• Dell ControlVault Driver WDRHG_WN64_3.3.14.68_A19_01
• Dell ControlVault Firmware GDFGW_3.3.15.0_A40_ZPE

When I finish installing the ControlVault Driver, in Device Manager/Biometric devices, the fingerprint sensor has a yellow triangle.

Moreover, when I try to update the firmware (ushupgrade.exe), I get the following message:

This program will update the ControlVault firmware
from 3.0.304.0 to 3.4.10.0.

Once started, do not interrupt process.

Going to stop Host Services.

Going to stop Host and DCP tasks.

Checking current ControlVault status.
Found ControlVault Chip Type: 5882 B0 CustID 1
ERROR: Missing files necessary for complete firmware update.
ERROR: Could not update ControlVault firmware.
Obtain complete firmware update package and try again.

All I ask for is a clear and straight forward way to install this *** fingerprint sensor. I used to use it a lot in the past, as quick login, but now it just drives me crazy knowing that I can't use it anymore.

Thank you very much.
