We have purchased the "Getting to Know ArcGIS for Desktop" book, and have successfully registered an account with ESRI.com. We then successfully installed the License Manager, and authorized our student license using the Authorization Code found at the back of the book.
We also successfully authorized the ArcGIS license through the ArcGIS Administrator application.
However, when we launch either ArcMap or ArcCatalog, the launch is interrupted with the error message:
ArcGIS Desktop Advanced is not authorized for use. Access the ArcGIS Administrator. Click on the product folder on the left (e.g. Desktop), then select the Single Use product you will be using and click the Authorized Now button. If you have already received an authorization file from ESRI, choose the third option 'I have received an authorization file from ESRI and am now ready to finish the authorization process'.
