GNA must be installed on a disk of sufficient size and accessible for reading and writing by the users (e.g. in the directory C:\users\<username>\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.

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.
