Hi OMARYOSS,

Rather strange that all other fingerprints are accepted and not the right index finger. 

Does it work with Fast Access? If you don't have Fast Access installed, then download and install the same - http://dell.to/1XCSjvX

Update the BIOS - http://dell.to/1MBd0HZ - and also reinstall the chipset and Dell Data Protection Security Tools and check if required.

Create a new local admin account and check if it works there.

Lastly, if your right index finger has scars / cuts - then it might possibly not work - see this thread where some users have reported the same issue - http://bit.ly/1NvEbPe

No Offense, but could you check if it works with a person in your family?

Keep us updated.

Have the same problem, I can't add my index, middle finger and thumb on right hand and my left hand's thumb. I think the problem is that I had registered these exact finger's prints previously when running a insider build. I've roll backed now to stable release.

Hi NIGHTLY SPARTAN,

Did you happen to try the steps as advised on my previous post on this thread?

Could you try FastAccess and let us know if it works?

Keep us updated.
