![]() When a newer JRE version is present (example: 6u15), older JRE versions ( example: 6u12) are installed in static mode only.A static JRE installation is never overwritten by another JRE version.A static JRE installation (example: 6u15) will ignore a previous patch-in-place installation of another JRE (example: 6u10). ![]() Some of the characteristics of a static JRE installation are as follows: NOTE: 8u371 and later JRE 8 releases will no longer support the STATIC argument. 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. A later version of the same JRE family will be installed in a separate directory. When a JRE is installed in the static mode, it will not be updated in place by newer versions. Instead, it updates the pre-existing c:/Program Files/Java/jre6 directory with the new 6u14 content. The default installation directory is c:/Program Files/Java/jre where n is the Java SE minor version number (for example, n = 6 for version 1.6.0_10).įor example, if a user has previously installed JRE 6u10 in the c:/Program Files/Java/jre6 directory, and now attempts to install JRE 6u14, the version 6u14 installer does not create a new directory. A JRE is installed in patch-in-place mode by default. The patch-in-place mode implies that when a version of the JRE exists on a machine, any updates belonging to the same JRE family will be done in place, meaning, the existing JRE will be patched with changes. For more information on silent install and uninstalling a silent installation, please see Silent Installation. The JRE may be installed in silent (unattended) or non-silent modes. JRE updates may be configured to patch a pre-existing installation or do a brand new installation. The JRE can now be installed in two configurations: patch-in-place and static. This resulted in unnecessary proliferation of unused JREs. In the past, when a user installed different versions of a Java Runtime Environment (JRE), the user would be left with multiple installation directories and several entries in the Add/Remove Programs dialog in the Control Panel. This feature is available only to installers running on Microsoft Windows. ![]() This document applies to JRE installers starting in Java SE 6 update 10 release.
