Install and Run Mars24
After downloading the appropriate Mars24 archive linked above, uncompress the archive file on your desktop. Within is a README text file with an explanation of the contents of the download, instructions on how to launch the application, and some notes on possible launch bugs and/or performance tuning.
We would like to point out the following possible installation and launch issues:
If you find that after download and installation, Mars24 won't start, a possible reason might be that you don't have a Java Runtime Engine (JRE) installed on your computer, or that it is not a Java 8 (or later) JRE. To check for this, use the website utility that looks for Java on your desktop and automatically downloads it if necessary. Go to Java.com and click on the "Free Download" button.
On Windows: You must extract Mars24 from the ZIP archive before you try to run it. If you simply open the ZIP file and then double-click on the Panoply icon, you will get a class-loader error because it cannot locate code files.
On Linux etc: The TGZ archive of Mars24 "generic" was created using a BSD tar on macOS. Using GNU-tar to uncompress the package will probably print several "Ignoring unknown extended header keyword" warning messages. You should be able to ignore these messages.
The Linux version may be launched using the "mars24.sh" shell script. If that fails, you should instead be able to launch the app by doublecicking on the Mars24.jar code file in the "jars" subdirectory.
