GNA does not require the definition of any particular environment variable (everything is taken into account by the execution script which was configured at the time of installation). GNA only requires that the Java Runtime Environment has been correctly installed on your machine. More precisely, the GNA script tries to locate the Java executable by various means. If it does not succeed, a warning message appears on the screen.
On Windows, you can provide the directory of your Java installation, after having checked it has been installed on your computer. Otherwise, use the archive bundled with the Java Runtime Environment.
On Linux and MacOS, the following message may appear:
"cannot find java location"
Several solutions are available to you for dealing with this problem:
Add the directory containing the Java executable to your path, or
Set the JAVA_HOME environment variable to point
to the Java installation directory, or
Set the JAVA_CMD environment variable to the
complete path of the Java executable.
If an error occurs during installation, you can analyse the messages written in the log file which may be found in the temporary directory.
If you still face problems, you can send a message to
