GNA must be installed on a disk of sufficient size and accessible for reading by all users (e.g. in the directory C:\Program Files\GNA). Before starting the installation, the archive corresponding to the target platform (Linux, Windows or MacOS) needs to be downloaded from the GNA web site. For Linux and Windows, it is possible to install GNA with a bundled JRE (Java Runtime Environment), in case Java has not been installed already. In addition, a thirdparty directory is available containing optional tools in the public domain.

A few seconds after launching the appropriate script, the GNA installer appears on the screen.

It is possible to cancel the installation at any time by clicking on the Cancel button.

Click on Next to continue the installation.
