In this article we explain why your license USB dongle may not be recognized by your computer and how to resolve this problem.

Before You Start

  • A dongle is a serialized hardware key attached to a USB port on a computer. 
  • A dongle is used to limit or lock software access to whomever has the dongle attached to their system through the associated license file.
  • Use of a dongle based license require three components:
    • The physical dongle attached to a USB port.
    • The proper dongle driver installed on the computer.
    • A license file that matches the host ID on the dongle.
  • When the computer successfully recognizes the dongle, a red light will illuminate on the key.


  • Your dongle driver may be out of date, an incorrect version, or missing.
  • Your dongle may be deprecated and need replacing.

Steps to Resolve

  • Update your dongle driver.  You should always download the latest version from the GEOSLOPE website:
