Installation instructions: After downloading and decompressing, the model should run upon clicking the icon for the application. The "IVE Model" folder may be placed anywhere, but the contents of the folder must remain in their original relationship to one another. All data files should be placed into the "IVE data" folder. If an error occurs upon first attempting to run the model, the Java Virtual Machine might not be installed.
