First you need to download the latest release of Zinc from the Zinc website. Zinc is downloadable as a file called ZincInstaller.jar.
ZincInstaller.jar is a self extracting installation program. The way that you run this program will depend on how Java is installed and what operating system you are using:
On Microsoft Windows you should be able to run the ZincInstaller.jar file by double clicking it in the Windows File Explorer.
On UNIX platforms you can run the installer with the command:
cd /where/you/put/ZincInstall.jar java -jar ZincInstaller.jar
If the java program is not in your PATH then you would have to enter the full path to it.
If you are the system administrator then you may wish to run the installer as the root user in order to make Zinc available to all users of the system.
On other operating systems you will have to consult the Java documentation to find out how to run .jar programs.
By default the installer uses a graphical interface:
Click on the Next buttons to advance through each stage of the installation. You will have the option to select an installation directory or accept the default.
You can run the installer in text mode with the UNIX command:
java -jar ZincInstaller.jar -text
A similar command can be used on other operating systems. This is useful for installing Zinc on a headless server.
