There are two ways to run FFGenie.
FFGenie is written and run on Java. The 'Launch' option will automatically configure your machine so that the Java settings are correct while the 'Download' option requires manual installation of Java.
The following splash screen should appear:

Then the following dialog should appear:
This signifies that FFGenie is being downloaded on the your machine. It's about 2MB in size. When you launch FFGenie in the future, it will only be downloaded again if a newer version of FFGenie is available. Otherwise, the version already downloaded will be the one that is used.
A security warning dialog may also appear, asking you whether you are sure you want to run FFGenie. You must answer yes for the program to run. This security dialog appears because FFGenie may need to open a connection to the respective competition sites to download data.
If all goes well, an application window titled "FFGenie 2009.2" should be created. Browse through to the tutorial for how to fully utilise FFGenie.
Download FFGenie at its sourceforge project page.
The zip file that is required is in the form 'FFGenie-<versionnumber>.zip. The zip file that contains 'src' in its name contains the source code for FFGenie, and cannot be used to run FFGenie directly. Unzip the zip file into a directory on your hard disk. Take note of the location.
Browse to this location in your operating system's file explorer. If Java is properly installed and configured, a simple execution of the FFGenie.jar file (double click) should launch FFGenie. However some machines have jar files associated with a zip archive program. In this case, launch a command prompt/shell script and navigate to the location noted above. Then type the following command to start FFGenie:
java -jar FFGenie.jar
If all goes well, an application window titled "FFGenie <version number>" should be created. Browse through to the tutorial for how to fully utilise FFGenie.
