Install and Run Mars24

The Mars24 package for Windows comes as a ZIP archive. You must manually extract this archive. Some versions of Windows allow you to run programs from a zipped archive without extraction, but if you try that with Mars24, it won't work.

The Mars24 archive contains a folder called Mars24J which holds the following items:

  • Mars24.exe application.
  • Martian landmarks file "marslandmarks.xml".
  • "Jars" directory containing program code.
  • "Sourcemaps" directory containing extra sample Mars maps.
  • A README file.
  • A subdirectory called "help" which includes user documentation.

To run Mars24, double-click on the Mars24.exe application icon.

Debugging Installation Problems

If you find that after download and installation, Mars24 for Windows won't start, a possible reason might be that you don't have a Java Runtime Engine (JRE) installed on your computer. To check for this, use the Sun utility that looks for Java on your desktop and automatically downloads it if necessary. Go to the Java.com website and click on the "Free Download" button.

Note: It is possible to have a Java plugin enabled in your web browser which allows you to run applets, but not have a JRE installed which allows you to run Java applications.
