Register extensions for ArcView or ArcEditor Single Use

Last Published: April 25, 2020


Instructions provided describe how to register the extensions for ArcGIS Single Use software.

Prior to beginning this process, ensure that you have a valid registration number for each extension, as well as the registration number for the Desktop Single Use software. If any of these numbers are missing, contact ESRI Customer Service before continuing.


Each extension for ArcGIS Single Use has its own unique registration number. The same UNK or EVA number cannot be used in multiple registration fields.

Follow the steps below to register ArcGIS Single Use and its extensions. The user logged in must have administrator privileges.

  1. Go to Start > Programs > ArcGIS > Desktop Administrator.
    [O-Image] Desktop Administrator
  2. In the left pane, click either 'Register ArcView and Extensions' or 'Register SingleUse and Extensions.'
  3. In the right pane, click Register Now.
  4. Select either of the following options, as they both guide you through the same wizard:

    'I have installed ArcView and need to register the software'


    'I have already registered the software and need to register additions ArcGIS extensions'
  5. Select the method to process the registration. The Internet method is the quickest.

    The remainder of this document assumes the Internet method was selected.
