2 Using a JRE MSI Installer Configuration File to Install the JRE
When installing the Java Runtime Environment (JRE) from the command line, you can use a configuration file to supplement the JRE MSI Installer command-line options.
You can create and use a configuration file to standardize installations and to specify options that are not available on the command line.
This section includes the following topics:
JRE MSI Installer Configuration Options
The following table lists the JRE MSI Installer configuration options and identifies which can be used in a configuration file and which can be used on the command line.
Options listed in the following table that can be used to create a configuration file are flagged Y in the Used in Config File column. Options flagged Y in the Used in Command Line column can be used in the command line when running the JRE MSI Installer. The options that are not available on the command line can be specified in the configuration file. See Running the JRE MSI Installer.
Note:
You can substitute Enable for 1 and Disable for 0.

Specifies the folder or directory into which the files are installed. Note: In 8u371 and later, the default installation directory changed to\ProgramFiles\Java\jre-$family
(jre-1.8). Beginning with JRE 8u381 b32,
use the RETAIN_ALL_VERSIONS=1 option to install
later versions of an installed JRE family without removing
preexisting JRE versions.

Note: 8u371 ended support for this option. TheREMOVEOLDERJRES option is
ignored beginning in 8u371. Customers that need to retain older JRE
versions should use the RETAIN_ALL_VERSIONS option
included in 8u381 b32 and later.
Before 8u371, using
REMOVEOLDERJRES=1 enabled uninstalling all
existing non-statically installed Java versions from a system during
the installation of the JRE.

Note: Added in 8u381 b32 and later. The JRE MSI installers for JRE 8u371 and later removed the default ability to retain older JRE versions already installed on disk. (TheREMOVEOLDERJRES option was disabled
in these versions.) Customers that need to retain older JRE versions
should use the RETAIN_ALL_VERSIONS=1 option in the
8u381 b32 or later.
Enables the installation of multiple JREs of the same family without removing preexisting JRE versions. When you set this option to In addition, if this option is enabled, the installer creates a registry that notifies the Java uninstall tool not to uninstall the JRE by default. When the out-of-date dialog is displayed, the option to uninstall the JRE will be deselected. See Uninstall Java Versions for more information.

Creating a JRE MSI Installer Configuration File
A configuration file provides an alternative to setting options on command line when running the JRE MSI Installer.
You can use the configuration file to standardize installations and to specify additional installation options that are not available on the command line.
- Either create a new file or open an existing configuration file in an ASCII text editor.
- Add or edit options in the configuration file. Refer to the Configuration Options table for available options.
- Save your configuration file as a text file in a directory of your choice.
- When you run the JRE MSI Installer (Running the JRE MSI Installer ), specify the path and file name of the configuration file in the JRE MSI Installer command.
- Installs the JRE in the directory
C:\java\jre. - Sets the security level for unsigned Java applications running in a browser to very high. Example of a Simple JRE MSI Installer Configuration File
INSTALLDIR=C:\java\jre
WEB_JAVA_SECURITY_LEVEL=VHSystem Runtime Configuration File
After installing a newer build of a JRE 8 version, the JRE MSI Installer creates the system runtime configuration file.
After using a configuration file to install the JRE, the JRE MSI Installer saves it
as a system runtime configuration file in C:\Program Files (x86)\Common
Files\Oracle\Java\java_settings.cfg
