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.
