Notes This chapter applies to 32-bit Windows and silent installation of the Java Runtime Environment (JRE). It is intended for: system administrators who want to deploy Java Plug-in and the JRE on multiple PCs in the Intranet environment without user interaction; companies with products that require the JRE, which they can silently install with their product.

## Introduction

JavaTM 2 Platform Runtime Environment (JRE) installations are built using InstallShield Developer 7, which is based on Microsoft Window Installer. This product contains built-in support for silent or unattended installations. This document tells how to silently install the JRE. Refer to http://support.installshield.com/ for complete information about silent installations.

## Running InstallShield in Silent Mode: Installation

Here is the command line for installing in silent mode:

> `<jre>.exe /s /v"/qn [ADDLOCAL=jrecore[,extra][,other_US] | ALL] [IEXPLORER=1] [NETSCAPE6=1] [MOZILLA=1] [INSTALLDIR=<drive>:\<install_path>][REBOOT=Suppress]"`

where

`<jre>.exe` is the single executable installer for the Java Runtime Environment (JRE); `ADDLOCAL`, if used, is either `jrecore[,extra][,other_US]` or `ALL`; `IEXPLORER=1`, if used, indicates that the Plug-in should be registered with the Internet Explorer browser; `NETSCAPE6=1`, if used, indicates that the Plug-in should be registered with Netscape 6 or later browsers; `MOZILLA=1` indicates that the Plug-in should be registered with Mozilla 1.1 and later browsers; `INSTALLDIR`, if used, specifies the drive and path of the installation; and `REBOOT=Suppress`, if used, indicates that if locked files are encountered the computer should not be rebooted.

If `ADDLOCAL=jrecore[,extra][,other_US]` is used,

> `jrecore` indicates the core of the JRE will be installed;

> `extra` (optional) indicates additional Fonts, Colors, and Soundbank will be installed;

> `other` (optional) indicates locale-specific `.jar` files will be installed.

If `ADDLOCAL=ALL` is used, then all the features will be installed.

If `ADDLOCAL` is not used, then only the recommended features will be installed: `jrecore` will be installed; `extra` will not be installed; `other` will be installed only if l10n support, other than English, is installed.

If `INSTALLDIR` is not specified, the installation will go into `C:\Program Files\java\j2re1.4.2` (default location).

Note The command is case sensitive and there must be no spaces in the features listed with `ADDLOCAL`.

### Examples

Suppose the JRE installer is `j2re-1_4_2-bin-b18-windows-i586-05_mar_2003.exe`; you want to install the JRE core and additional Fonts, Colors and Soundbank; and you want to register the Plug-in with Netscape 7 and Mozilla 1.3. Then the command would be:

> `j2re-1_4_2-bin-b18-windows-i586-05_mar_2003.exe /s /v"/qn ADDLOCAL=jrecore,extra NETSCAPE=1 MOZILLA=1"`

Or suppose you want all features to be installed; you only want to register the Plug-in with Internet Explorer; and you want the installation on the `D` drive at `java\jre`. Then the command line could be simply:

> `j2re-1_4_2-bin-b18-windows-i586-05_mar_2003.exe /s /v"/qn ADDLOCAL=ALL IEXPLORER=1 INSTALLDIR=D:\java\jre"`

You may find it convenient to use the "`start /w`" command, as that will cause MS-DOS to wait until the install is complete. For example:

> `start /w j2re-1_4_2-bin-b18-windows-i586-05_mar_2003.exe /s /v"/qn ADDLOCAL=ALL IEXPLORER=1 INSTALLDIR=D:\java\jre"`

## Running InstallShield in Silent Mode: Uninstalling

This is the command line for uninstalling in silent mode:

> `<jre>.exe /s /v"/qn [REBOOT=Suppress]" /x`

where `<jre>.exe` is the single executable installer for the JRE and `REBOOT=Suppress`, if used, indicates that if locked files are encountered the computer should not be rebooted.

### Example

> `j2re-1_4_2-bin-b18-windows-i586-05_mar_2003.exe /s /v"/qn REBOOT=Suppress" /x`

## Creating a Log File

If you want to create a log file describing the installation, add `/L C:\<path>setup.log` to the command. Note that this comes within the quote marks (""). For example:

> `j2re-1_4_2-bin-b18-windows-i586-05_mar_2003.exe /s/v"/qn ADDLOCAL=ALL /L C:\<path>setup.log`"

This will cause the log to be written to the `setup.log` file.

To verify if a silent installation succeeded, scroll to the end of the log file.
