In some scenario, you may need to reset all the credentials to ensure the fingerprint feature functions well.
· System which used previous enrollments has since been re-imaged or re-installed with a new operating system.
· If the TPM is disabled and/or cleared by the registered user.
If customer doesn’t reset the credentials correctly, they may run into the error message like" An error occurred during fingerprint enrolment. Please try to re-enroll this fingerprint. If you continue to receive this error, please contact technical support."
Due to the various Dell Notebook design implementations of the fingerprint sensor, this article highlights the three different procedures to delete the fingerprint enrolment from the sensor.
1) This applies to any business client system using external Dell UPEK sensor.
a) Attach the sensor to the system.
b) Navigate to the folder \Program Files\Wave Systems Corp\Dell Preboot Manager, and run deleteusers.exe (user must have administrator rights).
2) This applies to E5xx0 platforms which has built-in Authentic fingerprint sensor.
a) Navigate to the folder \Program Files\Dell\Security Device Driver Pack\Authentic AES2810 Fingerprint Reader\Tools
b) Run AESReset.exe as administrator and follow the on-screen instructions to reset the sensor.
3) For those platforms which use Broadcom USH chip to manage the credentials, there are two options to delete the credentials.
a) If Dell Control Point 1.4 or above version is installed, clear all credentials from credential vault tab.
Or b) Download latest ControlVault Firmware from support website. Copy the ushdiag.exe from the folder \DOS to a DOS bootable disk key. Boot up into the bootable DOS disk and run command "ushdiag –u –ccvo" to clear the credential vault objects.
In BIOS, set admin password, and then clear admin password to clear any BIOS Pre-Boot Authentication tables that may be stored.
1) For Vista or Win7 operating system, delete *.bin and *.xml files in the folder C:\ProgramData\Wave Systems Corp\UCS 2.0.
