A Note on terminology

Installing / Uninstalling - This is the process of loading the program on to windows. The program is installed by running pl5_setup.exe and is uninstalled by using the windows Add/Remove Program tool from the Control Panel. A single Pathloss 5 license can be downloaded and installed on many computers, but only one of these computers can be initialized at a time.

Initializing / Uninitializing - This is the process of activating a licence for use. A single Pathloss 5 license can be initialized on only one computer at a time. To move a licence from one computer to another, it must be uninitialized from the first computer before it is initialized on the second. The program need not be Uninstalled from either computer. This procedure is done from within the Pathloss 5 program.

Update vs Upgrade - Update means changing to a later build of the program. The licence email contains the link to download an update, updates are always free of charge. Upgrade means adding features such as Coverage or Interference. Upgrades are purchased from CTE and activated within the program.
