JRE Installer Options

This section discusses options for installation of the Java Runtime Environment (JRE) on Windows 32-bit platform. It is intended for:

• System Administrators deploying the Java JRE with Java Plug-in and Web Start technologies on multiple PCs in Intranet without user interaction.
• Vendors having products requiring the JRE. The JRE can be silently installed with their product.

The Installation section has the following topics:

Introduction

Java™ SE Runtime Environment (JRE) installations are built using Microsoft Window Installer (MSI) 2.0 technology. MSI contains built-in support for silent or unattended installations. This document tells how to manually install the JRE using the .exe that launches the MSI installation. The installer options are explained.

Command Line Install

In Java SE 6 The Windows offline installation command has the same syntax as the Windows Installation. The command is as follows:

 .exe [/lang=] [/s] [IEXPLORER=1] [MOZILLA=1] [INSTALLDIR=:\] [STATIC=1] 

• .exe is the single executable installer for the Java Runtime Environment (JRE)
• /lang= , if used, sets the localized language for the installer. For a complete list, please see Language IDs.
• /s , if used, indicates silent installation
• IEXPLORER=1 , if used, indicates that the Plug-in should be registered as the default Java VM with the Internet Explorer browser
• MOZILLA=1 indicates that the Plug-in should be registered with Mozilla 1.1 and later and Netscape browsers
• INSTALLDIR , if used, specifies the drive and path of the installation
• If INSTALLDIR is not specified, the installation will go into C:\Program Files\java\jre1.6.0 (default location).
• STATIC=1 , if used, specifies a static installation. This option is available in the 6u10 release and above. For more information on static install, please see Java Runtime Environment Configuration.

The following options have been deprecated starting in release Java SE 6 update 10:

Installation Configurations

Example 1

Suppose the JRE installer is jre-6-rc-windows-i586.exe and you want to install the following configuration:

• Perform a Windows Installation
• Install the JRE core, additional fonts, colors, and Soundbank
• Register the Plug-in with Netscape 7 and Mozilla 1.3

The command to install the above mentioned configuration is as follows:

jre-6-rc-windows-i586.exe /s MOZILLA=1

Example 2

Suppose the JRE installer is jre-6-rc-windows-i586.exe and you want to install the following configuration:

• Perform a Windows Offline Installation and install the JRE on D drive at java\jre
• Have all features of the JRE installed
• Register the Plug-in with Internet Explorer

The command to install the above mentioned configuration is as follows:

jre-6-rc-windows-i586.exe /s IEXPLORER=1 INSTALLDIR=D:\java\jre

To keep the MS-DOS window open, until the installation of JRE is complete use the start /w command as follows:

start /w jre-6-rc-windows-i586.exe /s MOZILLA=1

Creating a Log File

Log file can be used to verify if an installation succeeded. To create a log file describing the installation append /L C:\setup.log to the install command and scroll to the end of the log file to verify.

Installation Example

The following is an example for installation:

jre-6-rc-windows-i586.exe /s /L C:\setup.log

The above command causes the log to be written to the setup.log file.

17 Windows JRE Installer Options

This page describes options for installing, configuring, and creating a log file for the Windows Java Runtime Environment.

This page contains the following topics:

See «JDK 8 and JRE 8 Installation Start Here» for general information about installing JDK 8 and JRE 8.

Introduction

This page describes options for installation of the Java SE Runtime Environment (JRE) on Windows 32-bit platform. It is intended for:

• System administrators deploying the JRE with Java Plug-in and Java Web Start technologies on multiple PCs in their Intranet without user interaction.
• Vendors having products requiring the JRE. The JRE can be silently (non-interactively from the command line) installed with their product.

JRE installers are built using Microsoft Window Installer (MSI) 2.0 technology. MSI contains built-in support for silent installations. This topic explains how to manually install the JRE using the .exe file that runs the MSI.

Command-Line Installation

This section describes the command-line options for the JRE Windows Offline Installer. Run the installer as follows:

jre [INSTALLCFG=configuration_file_path] [options]

• jre refers to the JRE Windows Offline Installer base file name (for example, jre-8u05-windows-i586.exe ).
• INSTALLCFG= configuration_file_path specifies the path of the installer configuration file. See «Installing With a Configuration File» for more information.
• options are options with specified values separated by spaces. Use the same options as listed in Table 20-1, «Configuration File Options». In addition, you may use the option /s for the JRE Windows Offline Installer to perform a silent installation.

Static Installation

If you perform a static installation of the JRE (by specifying the command-line or configuration file option STATIC=1 ), then the Java Auto Update feature will leave that JRE installed during a Java update. A later version of the same JRE family will be installed in a separate directory. This mode ensures that vendors, who require a specific version of the JRE for their product, can be certain that the JRE will not be overwritten by a newer version.

The default installation directory of a static JRE is C:\Program Files (x86)\Java\jre n (for 32-bit versions) or C:\Program Files\Java\jre n (for 64-bit versions), where n is the full Java SE release and update number (for example, n = 1.8.0_20 for release 8 update 20).

Creating a Log File

Use a log file to verify that an installation succeeded. To create a log file describing the installation, append /L C:\ path setup.log to the install command and scroll to the end of the log file to verify.

The following is an example of creating a log file:

jre-8-windows-i586.exe /s /L C:\pathsetup.log

This example causes the log to be written to the path setup.log file.
