Adding Extensions to ArcGIS Desktop

Blog Post created by timothy_hales-esristaff Employee on Jan 31, 2012
ArcGIS  Desktop has a lot of useful extensions beyond the core product. Some of the available extensions include ArcGIS Spatial Analyst, ArcGIS 3D Analyst, ArcGIS Network Analyst, and ArcGIS Data Interoperability. Each of the  extensions can be evaluated before purchasing.

If you have chosen to evaluate or purchase an extension and found that  you were unable to activate the extension on your machine, then there are a  couple areas to check.

Check that the extension has been  installed (Customize > Extensions)

The extension  will be listed in this dialog if has been installed. An empty list means no extensions have been  installed.image002.jpgimage002.jpg

If the extension has not been  installed, then you will need to modify the ArcGIS Desktop installation to  include the extension.
  1. Open Programs and Features (Add/Remove Programs) from the Control Panel.
  2. Right-click the ArcGIS Desktop 10 > Uninstall/Change.
  3. Navigate to ArcGIS Desktop 10 Setup > Modify.
  4. Select the extensions to be installed by changing the drop down menu status beside each one.
  5. Click Next to follow the remaining installation instructions.(Note that the system may request that you provide the installation media.)image004.jpg

Once you have confirmed that the  extension has been installed, activate the extension (Customize > Extension).

Check that the extension can be  activated

Activating an extension from the  Extensions window will allow that functionality to be available.Note that you must  activate the extension in each product that you use (ArcMap, ArcCatalog,  ArcScene, etc).image006.jpg If you are unable to activate an  extension and get an error message that the license is not currently available,  please check the ArcGIS Administrator to see if the extension is available on  your existing system or through the license manager. The license may already be checked out by  another user, or it may not be authorized for use on the machine.
