Thank you for downloading this release of the JavaTM Platform, Standard Edition Development Kit (JDKTM). The JDK is a development environment for building applications, applets, and components using the Java programming language.
WARNING: These older versions of the JRE and JDK are provided to help developers debug issues in older systems. They are not updated with the latest security patches and are not recommended for use in production.

If you are downloading the JDK installer for 64-bit systems for update 9 Minor 1, Security 1, and Patch 1, then the file name jdk-9.minor.security.patch_windows-x64_bin.exe becomes jdk-22.214.171.124_windows-x64_bin.exe.
If you are downloading the JRE installer for 64-bit systems for update 9 Minor 1, Security 1, and Patch 1, then the file name jre-9.minor.security.patch_windows-x64_bin.exe becomes jre-126.96.36.199_windows-x64_bin.exe.
The following table lists example installation scenarios and the commands required to perform them. The notation jdk stands for the downloaded installer file base name, such as jdk-9_windows-x64_bin.exe.

With Java Web Start, you can download and run applications, such as a complete spreadsheet program or an internet chat client, without going through complicated installation procedures. With Java Web Start, you run applications simply by clicking a web page link. If the application is not present on your computer, Java Web Start automatically downloads all necessary files. It then caches the files on your computer so that the application is always ready to be run anytime that you want - either from an icon on your desktop or from the browser link. No matter which method you use to run the application, the most current, available version of the application is always presented to you.
If you have a previous version of Java Web Start, do not uninstall it. Uninstalling it will cause the download cache to be cleared, and all previously installed Java Web Start application data will have to be downloaded again. The new version will write over previous installations and automatically update browsers to use the new version. The configuration files and the program files folder used by Java Web Start have changed, but all your settings will remain intact after the upgrade because Java Web Start will translate your settings to the new form.
To avoid seeing the misleading message, either press F5 or reopen the dialog box. Any Java Web Start application that was downloaded and cached with the JDK or JRE will no longer appear in the list of currently installed programs.
When the installed JRE falls below the security baseline or passes its built-in expiration date, an additional warning is shown to users to update their installed JRE to the latest version. For businesses that manage the update process centrally, users attempting to update their JRE individually, may cause problems.
In Microsoft Windows, when you create a new file in Microsoft Notepad and then save it for the first time, Notepad usually adds the .txt extension to the file name. Therefore, a file that you name Test.java is actually saved as Test.java.txt. Note that you cannot see the .txt extension unless you turn on the viewing of file extensions (in Microsoft Windows Explorer, deselect Hide file extensions for known file types under Folder Options). To prevent the .txt extension, enclose the file name in quotation marks, such as "Test.java" when entering information in the Save As dialog box.
The JRE bootstrap installer uses the system Internet Connection settings to connect to the web for downloading extra files. If you are behind a firewall and require proxy settings, then ensure that the proxy settings in Internet Options/Internet Properties are set up properly (select Start, then Control Panel, then Internet Options/Internet Properties, then Connections, and then LAN Settings). If you can browse the external web (for example, outside the firewall) with Internet Explorer, then your proxy settings are properly set up. The installer does not understand the proxy settings specified in Netscape/Mozilla.
The message is part of the Java Auto Update mechanism, which detects at user login time if a newer version of the JRE is available for download. In the system tray, click the Java Update icon to download and install the update.
To address these problems, ensure that the third-party downloader applications are turned off and the network connection is configured properly. Also, if a proxy is in use, then ensure that the proxy authentication is turned off.
See Error 1722: Problem with Windows Installer Package. If you encounter any other errors or issues, then you can access Java Help Center, which contains solutions for issues that you might encounter when downloading and installing Java on your system. In particular, you can search for solutions by error number. Searching for "Error 1722" returns a solution to this issue.
If you are installing ImageJ2 on Windows, we strongly recommend that you storeyour ImageJ2.app directory somewhere in your user space(e.g., C:\Users\[your name]\ImageJ2.app) rather than in C:\Program Files orother system-wide directory. If you move ImageJ2.app to such a directory, modernversions of Windows will deny ImageJ2 write permission to its own directorystructure, preventing it from being able to update. See alsoimagej/imagej#72.

Note on 32-bit versus 64-bit versions: You only need the 64-bit version of the SAP Java Connector if you are using a 64-bit Java VM. If you have to use a 32-bit Java VM on a 64-bit platform, download and use the 32-bit version of JCo. The 64-bit variant should always be preferred on 64-bit platforms.Some JVMs offer both modes: 32-bit as well as 64-bit. In this case you need to start the JVM with an additional start-up parameter to specify the mode. Usually these are options -d32 and -d64; please consult the JVM documentation for further details.

Updates happen by installing a new version over an older version. See also the installation instructions included in the JCo SDK download archive. In general, a new SAP Java Connector patch level is downwards compatible to the previous patch levels of the same release.
The SAP Java Connector (JCo) and the SAP Java IDoc Library (JIDocLib) are available free of charge and can be downloaded from the SAP Support Portal. The license terms are pointed out on the download pages and in the documentation of these components.
I installed the jdk 1.6u7, and then I open firefox, I see there is a java console 6.0.07 in extension, but in plugins, there is no java. and I can't open java website, it shows I don't install java in my machine, but actually, I have installed jdk 1.6u7. I think only if the java exists in plugins, the website can get the jvm and run.
You would need JRE (Java Runtime Environment) to run Java programs. You can try to click the download button on the page (above image) or you can download the latest version here: -downloads-1637588.html
I download the jdk file: jdk-6u7-windows-i586-p.exe, after I click it and install, it installed both the jdk and jre, I can see 2 folders: C:\Program Files (x86)\Java\jdk1.6.0_07 and C:\Program Files (x86)\Java\jre1.6.0_07.
The Java Update feature lets you check for updates from the Java (32-bit) Update tab in Windows Control Panel. To update java manually, go to and download the latest version of Java, currently Java 7 Update 5, then close Firefox and run the installer. You will then see Java(TM) Platform SE 7 U5 in the Firefox Add-ons Manager Plugins list when you next open Firefox. You can check your Java version using the test links here.
Hi, New laptop with Win 11 installed. Line 6 Edit install fails to download jre_setup.exe for Java Runtime v1.6 32-bit.Running Line 6 Edit even with the latest JRE 1.8 raises the error that JRE 1.6 32-bit is required.This is to edit my Pod 2.0 which still has some great legacy tones but I need Edit to change values like noise gate threshold.Does anyone have a solution for this, or an alternate method for controlling Pod 2.0? 2b1af7f3a8
