#DO I NEED JAVA 7 UPDATE 45 INSTALL#
The default installation directory of a patch-in-place installation is C:/Program Files/Java/jre, where is the Java SE minor version number.įor example, if a user previously installed JRE 7 Update 1 in the default directory C:/Program Files/Java/jre7 directory, and now attempts to install JRE 7 Update 3, the JRE 7 Update 3 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, see Command-Line Installation in JRE Installer Options. The JRE may be installed in silent (non-interactive) or nonsilent (interactive) modes.

JRE updates may be configured to patch an existing installation or to 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 the JRE, the user would be left with multiple installation directories and several entries in the Add/Remove Programs dialog in the Control Panel. Note: This information may refer to versions of the JRE that do not exist these versions are used to demonstrate the concepts of patch-in-place and static JRE installations. This information applies to Java SE Runtime Environment (JRE) installers running on Microsoft Windows. See JDK 7 and JRE 7 Installation Guide for general information about installing JDK 7 and JRE 7.
