Installing and running Modsak

Windows installation

To install Modsak under Windows, download and execute the file modsak3.15_setup.exe. You can then run Modsak from the Start menu or by using the desktop icon.

Linux installation

To install Modsak under Linux, download the file modsak3.15.jar and put it in any convenient directory. You can then run Modsak using the command:

java -jar modsak3.15.jar

You will, of course, need to use the full pathname for modsak3.15.jar if it's not in your current directory. You will probably want to create a shortcut, launcher, shell script, or whatever to save you having to keep typing the above command.

Java requirement

Since Modsak is written in Java, you will need a copy of the Java JRE (version 6 or later) in order to run it. If you are unable to run Modsak, try the command:

java -version

If you get an error from this command, then you do not have the JRE installed, and you will have to download it from Oracle.


Before you can use Modsak you will need to get a registration key.
