# I-X: Downloading and Installing |

Home | I-X Components | I-X Documentation | Downloading and Installing I-X | Applications | More Background

From this page the complete current public release of the I-X software can be downloaded. To run I-X, a Java Runtime Environment (JRE) needs to be installed before I-X can be used. The release includes:

- the complete I-X system (Java classes to run in a JRE)
- the complete documentation including examples
- some project-specific application packages
- the full software licence

Note that the public release does not include the source code.

The current software licence essentially permits the use of I-X for academic, non-commercial purposes only. The US government, having funded part of this work, has special rights. Read the full licence for details.

## Instructions for Downloading and Installing I-X

Downloading and installing I-X consists of three major steps:

1. Download the zip-file: Go to the public release section below and press the download button. The file that must be downloaded is called something like "`ix-`N`-core.zip`", where N is the latest version number (e.g. the I-X version 4.2 is called "`ix-4.2-core.zip`"). Your browser should then bring up a window asking you what you want to do with this file type (`".zip"`). The best way to proceed is to save the file somewhere on your computer (remember where!).
2. Unpack the zip-file: Unzip the I-X core. The exact method for doing this depends on the operating system you are using. For instance, under Windows, you can unzip the core using a tool such as Winzip. For example, if you unzip the core into the D drive, this will generate the "`D:\ix-4.2\...`" directory. Under Unix, you can use the `unzip`-command to unzip the file to a location of your choosing. In the documentation, we use the term base directory, or `<ix-base>`, to refer to this directory.
3. Run the test-script: If you use Windows, go to the directory "<ix-base>/scripts/win/" and run the script called "`test-setup.bat`". This should produce a few lines of output, essentially telling you which version of Java is being used. Unless one of the lines reads "'java' is not recognized as an internal or external command, operable program or batch file.", it should be fine (see also the Windows readme-file). Currently there is no equivalent script for Unix or other operating systems, but a simple "`java -version`" should at least tell you whether a JRE can be found in your environment(see also the Unix readme-file).

I-X is now successfully installed on your machine.

## The I-X Public Release

## Support

Currently, the support for I-X is rather limited. In the first instance, you should consult the documentation that is part of the public release version (see "<ix-base>/doc/"). If this does not answer all your questions, try the following:

- The online documentation is identical to what is provided in the current public release.
- Send an e-mail to i-x@aiai.ed.ac.uk.
