Installation Instructions Notation

For any text in this document that contains the following notation, you must substitute the advisable update version number for the notation.

<version>

For example, if y'all were downloading the Offline JRE Installer for 32-bit systems for update 1.7.0_01, the file name jre-7<version>-windows-i586.exe would become jre-7u1-windows-i586.exe.

Similarly, if you were downloading the Offline JRE Installer for 64-bit systems for update 1.7.0_01, the file proper noun jre-7<version>-windows-x64.exe would go: jre-7u1-windows-x64.exe.

Installation Instructions

Install the JRE by doing the following:

• Downloading the installer
• Running the installer

Downloading the Installer

Y'all have a pick of the following kinds of JRE installers that you can download:

• Windows x86 Online: jre-vii<version>-windows-i586-iftw.exe (The messages iftw mean "install from the web.")
• Windows x86 Offline: jre-7<version>-windows-i586.exe
• Windows x64: jre-7<version>-windows-x64.exe

Note:

• The Windows x86 Online Installer is a small program that will download more installer files based on your arrangement configuration. Using this installer can help you avoid downloading large amounts of unnecessary files. For more information, meet Windows Online Installation and Java Update FAQ.
• The Windows x86 Offline Installer, as well as the installers for 64-bit systems, incorporate everything needed to install the JRE.

Click the JRE Download link for the installer yous want to use. A dialog box opens. Depending on your browser, click Salve or Salve File to save the JRE installer without installing information technology. Verify that you lot have downloaded the entire file by comparing the size of the file y'all downloaded with the expected size shown on the download page. Alternatively, (depending on your browser) click Run or Open to run the JRE installer from your browser.

Running the Installer

Notation: You must have authoritative permissions in order to install the JRE.

If you saved the JRE installer to your computer, run the installer by double-clicking it. Follow the instructions the installer provides. The installer notifies you if Java content is disabled in web browsers, and provides instructions for enabling it. If you previously chose to hide some of the security prompts for applets and Java Web Start applications, the installer provides an selection for restoring the prompts. When yous are finished with the installation, yous can delete the downloaded file to recover disk space.

The installer may enquire you to reboot your computer if you chose not to restart an internet browser when it prompted y'all to exercise so.

Note:

• The public JRE installed with the JDK is not registered. (This as well applies to the 64-bit version of the JDK.) Y'all must set the PATH environment variable to point to JAVA_HOME\bin (where JAVA_HOME is the location where you installed the public JRE) to register the JRE. See Private Versus Public JRE for more data about the public JRE.

• Installers for JRE 7u6 and later install the JavaFX runtime and integrate it into the JRE installation directory. Installers for JRE 7u2 to 7u5 install the JRE first, and then start the the JavaFX runtime installer, which installs the JavaFX runtime in the default directory C:\Programme Files\Oracle\JavaFX 2.0 Runtime or C:\Programme Files (x86)\Oracle\JavaFX 2.0 Runtime on 64-bit operating systems. If you desire to install the JavaFX runtime (version 2.0.2) with JRE 7u1 or earlier, see Installing JavaFX for more than information.

• JRE 7u6 and later include Java Access Bridge. By default, Java Access Span is disabled. To enable it, see Enabling Java Admission Bridge.

Java Start Menu

Starting with JDK 7u40 release, Coffee card items are added to the Windows Kickoff Menu to provide like shooting fish in a barrel access to Java resources.

During JRE install, a Java folder is created in the Windows Start Bill of fare, which contains the following items:

• About Java: opens an Virtually Java window that shows the latest JRE version installed on the system.
• Cheque for Updates: opens the Java Command Console with focus on the Update tab.
• Configure Java: opens the Java Control Panel with focus on the General tab.
• Get Help: opens the URL http://java.com/en/download/help/index.xml.
• Visit Java.com: opens the URL http://java.com/en/.

During JRE install and uninstall processes, the appropriate showtime card items are updated to exist associated with the latest JRE version on the organisation.

Java Plug-in

Coffee Plug-in technology, included as part of the JRE, establishes a connectedness between popular browsers and the Java platform. This connection enables applets on web sites to exist run within a browser on the desktop. Coffee Plug-in is automatically enabled for supported web browsers during installation of the JRE. No user intervention is necessary. See Applet Programmer's Guide for more information most Java Plug-in engineering.

Annotation: In Java SE 7, the version of Java Plug-in that is bachelor in versions of the JRE prior to Java SE 6 Update x has been deprecated. However, this earlier version of Java Plug-in is still shipped with Java SE 7 for compatibility purposes just is no longer fully supported. Information technology will be removed in a hereafter release. For backward compatibility purposes, y'all can specify which Java Plug-in is used to run applets in the Java Command Panel. To specify this, run Coffee Control Panel, get to the Advanced tab, Java Plug-in node, and toggle the bank check box labeled Enable the next-generation Java Plug-in. See Java Control Panel for more information. In improver, yous tin can employ the Java Control Panel to manage multiple JRE versions used for applet execution.

Coffee Spider web Start

Coffee Spider web Offset is an application-deployment engineering that gives you lot the power to run full-featured applications with a single click from your Spider web browser. You can now download and run applications, such equally a complete spreadsheet program or an Net chat client, without going through complicated installation procedures. With Coffee Web First, you run applications only past clicking a spider web page link. If the application is not present on your calculator, Java Spider web First automatically downloads all necessary files. It then caches the files on your computer and then the application is e'er fix to be run someday you want — either from an icon on your desktop or from the browser link. No affair which method you use to run the application, the near current, available version of the application is e'er presented to you. See Java Spider web Start for more than information.

This section covers the following topics:

• Upgrading from Previous Versions
• Uninstallation

Upgrading from Previous Versions

If you have a previous version of Java Web Get-go, do not uninstall information technology. Uninstalling it will cause the download cache to be cleared, and all previously installed Java Web Start application data volition take to be downloaded once more. This new version will write over previous installations and automatically update browsers to use this new version. The configuration files and the program files folder used by Java Spider web Start have changed, but all your settings volition remain intact after the upgrade because Java Spider web Start will translate your settings to the new form.

Uninstallation

The only fashion to uninstall Coffee Web Commencement is to uninstall the JDK/JRE. Uninstalling the JDK/JRE will non, notwithstanding, remove the enshroud for previous versions of Coffee Web Beginning. Previous releases accept carve up uninstall instructions for Coffee Spider web Start.

Note: You may come across a misleading message if you do the post-obit:

• Download and enshroud a Java Web Start application with the JDK or JRE.
• Remove the JDK or JRE using "Add or Remove Programs" from the Windows Control Console.
• Remove the Java Web Commencement awarding using "Add together or Remove Programs."

When y'all remove the application, you run across an "Uninstaller Error" dialog box saying "An error occurred while trying to remove Java-Awarding: <name> App. It may accept already been uninstalled. Would you like to remove Java-Application: <name> App from the Add or Remove program listing?" If you say yes to this, then you volition run into another "Uninstaller Error" dialog box saying "You practise not take sufficient access to remove Java-Application: <name> App from the Add together or Remove Plan listing. Please contact your organisation administrator." This is the misleading message. Information technology implies that the trouble is due to privileges. It is not. The trouble is that you have already removed the Java Web Start application when yous removed JDK or JRE, but this is not reflected in the "Add or Remove Programs" dialog box until information technology is refreshed by pressing F5 or it is closed and reopened.

To avoid seeing this misleading bulletin, either press F5 or close and reopen the dialog box. Any Coffee Web Start application that was downloaded and cached with the JDK or JRE volition no longer appear in the list of currently installed programs.

Java Update Feature

For issues related to the Coffee Update feature, see Java Update.

Silent Installation

To install the JRE silently or non-interactively, which is useful for installing on multiple computers, run into Command-Line Installation in JRE Installer Options.

Silent Uninstallation

Yous can use the command line for uninstalling the JRE.

Use the post-obit command to uninstall the JRE in silent style:

              msiexec.exe/X{UninstallString}                          

For example, to uninstall Coffee seven update 271, run the control:

              msiexec.exe/X{26A24AE4-039D-4CA4-87B4-2F64170271FF}            

To observe the UninstallString, see "Finding the JRE Registry Key and UninstallString".

Note:

• This command tin can be run from anywhere.

• The msiexec.exe executable is located in the windows system directory.

• A reboot is required only if some files are in use during uninstallation; information technology is non necessary everytime. However, to manually suppress reboot while uninstalling, append REBOOT=R selection to the command.

• Append /l "C:\<path>setup.log" pick to the command if you want to create a log file describing the uninstallation condition.

Windows Installer dialog appears prompting y'all for confirmation. Click Yes to uninstall JRE.

Finding the JRE Registry Key and UninstallString Value

1. Go to Get-go and type regedit.

2. In the Registry Editor, go to HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Uninstall.

   Under the Uninstall folder, you will find many registry entries within curly brackets.

3. Click Edit so Notice.

   
   

   Annotation:

   Highlight Uninstall folder before performing search for a particular registry.

   
   

4. Enter version string equally value to find respective registry primal. For JRE registry key, enter 1.seven.0_271.

   The registry central is highlighted on the right-hand side of the pane and values of diverse uninstall strings are displayed on the left-paw pane.

5. Note the value of the UninstallString.

Installation of JRE on 64-Bit Windows Computers

64-bit Windows operating systems (which may be Windows 7, Windows eight or Vista) come up with a 32-fleck Cyberspace Explorer (IE) browser as the standard (default) for viewing web pages. These operating systems also include a 64-flake Net Explorer browser. Notwithstanding, using it is optional, and information technology must exist explicitly selected to view web pages. Note that because some web content may not work properly in a 64-bit browser, it is recommended that you use the default 32-fleck browser and install the 32-fleck JRE.

Note: The Windows Online Installer and Java Update features are not applicable to 64-flake architecture.

The following sections can help you determine which JRE to install:

• Verifying Your Version of Windows
• Verifying Your Browser
• Choosing Which JRE Installer to Download

Verifying Your Version of Windows

See 32-scrap and 64-bit Windows: often asked questions to determine if your system is running a 64-scrap version of Windows.

Verifying Your Browser

Follow these steps to determine whether y'all are using a 32-chip or 64-bit version of Internet Explorer:

1. Start Internet Explorer.
2. In the carte du jour bar, click Help.
3. Select Nearly Internet Explorer, which will open an data window.

Follow one of the post-obit methods to determine whether you lot are using a 64-flake version of Firefox:

• Check the About Firefox panel.
• Type about:back up in the browser address.

If y'all running 64-flake version of Firefox, information technology may be indicated as 64-bit (for example, Win64); otherwise, information technology is a 32-chip version of Firefox.

Note: The 64-chip JRE is presented every bit a download option automatically for 64-flake Cyberspace Explorer and 64-bit Firefox for Windows users.

Choosing Which JRE Installer to Download

Download the JRE installer, depending on which browser you lot have installed:

• 32-chip browser: download the 32-bit JRE installer (use either the Windows x86 Offline or Online installer)
• 64-flake browser: download the 64-bit JRE installer
• Both 32-bit and 64-bit browsers: download both the 32-bit and 64-fleck JRE installers, respectively
