Download the Java Runtime Environment (JRE) for your operating system. (Approximate download size : 50 MB).
The latest version is 1.8 (named "Java SE Runtime Environment 8u131").
If you have already a Java Runtime Environment 1.6 or 1.7 installed you can keep it to run JANIS, but it is recommended to upgrade it to the latest version as this will increase security as weel as improve speed, integration and also correct some bugs.
