Information

ZCB requires that the Java Runtime Environment (JRE), version 7 or higher, be installed on the system. The ZCB user interface cannot run without the JRE, and backups cannot be configured or managed without the user interface.

The ZCB installation process checks for the appropriate version of the JRE on the system, and prompts the user to install the JRE if it is not detected. Installation cannot proceed until the JRE has been properly installed. 

Simple Java Installation

Easy-to-install Java packages are available for download from http://java.com/en/download/manual.jsp. These Java packages includes both the Java Runtime Environment, which is required by ZCB, and the Java browser plugin, which is not required.

Simply download and run the appropriate installation package for your system. ZCB requires that machines running 64-bit Windows have the the 64-bit version of Java installed. Likewise, ZCB on 32-bit Windows machines require 32-bit Java.

A More Secure Java Installation

If necessary, additional steps can be taken to increase the security of a Java installation. 

Server administrators may wish to install only the Java Runtime Environment. Alternately, administrators may disable the Java browser plugin. Most Java-related security issues can be traced to the Java browser plugin. 

How to install only the Java Runtime Environment

The Java Runtime Environment can be downloaded as a standalone product without the browser plugin.
