Available with Data Reviewer license.
ArcGIS 10.3.1Data Reviewer for Desktop uses your current ArcGIS license system and requires authorization to be activated. You need to add the Data Reviewer feature to the ArcGIS License Manager. Once your license manager has been updated, you can activate the feature through the Extensions dialog box in ArcGIS for Desktop.
Authorization information
Single Use products require authorization of the software for use on individual machines. You will need the authorization codes that Esri Customer Service (http://www.esri.com/about-esri/contact) sent to the contact email address referenced in the sales order. This email included the authorization codes that have been issued for each license in the order. For an ArcGIS for Desktop Single Use product, the authorization code starts with the letters ESU or EVA, followed by nine numeric digits (for example, ESU123456789).
