Prerequisites

Ja.NET SE, to date, has been tested only on Microsoft Windows XP with the .NET 3.5 framework. While we have no reason to believe it won't work on other versions of Windows, you should be aware that it has not been tested on anything else. Also, at this time, we are not providing a 64-bit Windows version for download. We hope to be able to post one in the near future. 

You will note we have not produced a version for Mono. At this point, no work is underway to do so. We are looking for volunteers to help out in this area.

In order to successfully install Ja.NET SE, you need to be logged in under an account that has administrator privileges. You need to have .NET 3.5 and the Visual C++ 2008 C runtime libraries installed on your machine, as well. If you install Ja.NET SE using the supplied .MSI files, the Visual C++ 2008 C runtime libraries will be installed for you as part of the Ja.NET SE install. You will still need to download and install .NET 3.5 either directly or indirectly by installing one of the Visual Studio products.

If you manually install Ja.NET SE using the provided .ZIP files, you have to check for these prerequisites yourself.  If you find you are missing any of them, you can download them from the Microsoft Download Center.

Installing

The simplest way to install any of the Ja.NET SE packages on Windows is to use the Windows installer service. To do this, simply download the appropriate .MSI file for the SE package you wish to install (i.e., JDK or JRE) and run it on the machine. 

The installation script will check to ensure that the correct .NET framework and Visual C++ runtime libraries are installed. If it finds the .NET framework is not installed, it will stop the installation and give you the opportunity to download and install it before continuing the installation of Ja.NET SE. Once the prerequisites are installed, the script will ask where you'd like to install Ja.NET SE, and then proceed to copy and configure the files as needed. Should you want to uninstall or repair a Ja.NET SE installation, you can use either the Windows Control Panel to add to or remove the installation, or simply rerun the same .MSI file.

If you wish to manually install Ja.NET SE, you will want to download the .ZIP file corresponding with the Ja.NET SE package (i.e., JDK or JRE) you wish to install. Once you have done this, you can follow these step by step instructions to get an installation up and running.

Configuring

Once you have completed the installation, either manually or by using the installer, the last thing you'll want to do is to set your PATH environment variable to include the path to the Ja.NET SE JDK or JRE bin directory. The bin directory can be found in JANET_INSTALL\bin.
