Activating a license transfers the license rights from the Harris Download and Licensing Center to a node-locked (local) computer or license server. It also creates the features and quantities of licenses that enable the software to run. When you purchase Harris Geospatial products, you will receive an email with an activation code to use to activate your software license. The license is a concurrent process license for each product that was purchased. These instructions describe how to activate on a local computer (node-locked licenses). Licenses are activated over the Internet. To open the License Administrator Tool described in this section, use one of the following: Linux: From a terminal window, launch the harrislicense command from the `$INSTALL_DIR/idlxx/bin` directory. Sudo or root permissions are required. Mac: From a Finder window, double-click the LicenseAdminstrator.app icon located under the `$INSTALL_DIR/idlxx` directory. Administrator privileges are required. ##Activate Licenses## 1. In the License Administrator Tool, click `Activate Local License`. 2. Enter the activation codes. 3.
