  3. If the machine is running Windows or Mac go to step 4.  If the machine is running Linux or Unix create a properties file called app.properties in the WORKING_DIRECTORY or download this example of the app.properties file.  Edit the app.properties file to enter the valid credentials by following the descriptions given on the table provided here.  

  4. Launch the application. For Linux/Unix go to step 17.
