BIOS update error

Hello

I am trying to update my BIOS, but when I install the update, I receive this message:

The system is currently under Intel Anti-Theft Technology 4.0 protection. Please in-enroll the client before performs the BIOS update.

I don't have Lojack on my laptop. This model's the Inspiron 15R 7520.

Can someone assist me with this?

Thanks
