The procedure to install Java broadly consists of:

1. Download and Install
2. Test Installation

» Windows System Requirements
 

Note: Installing Java requires that you can gain administrator access to Windows on your computer.

Download and Install

It is recommended, before you proceed with online installation you may want to disable your Internet firewall. In some cases the default firewall settings are set to reject all automatic or online installations such as the Java online installation. If the firewall is not configured appropriately it may stall the download/install operation of Java under certain conditions. Refer to your specific Internet firewall manual for instructions on how to disable your Internet Firewall.

• Click on Windows Online
• This will download an executable file (example: jre-8u333-windows-i586-iftw.exe) to the default download location on the local system
  Note: You can opt to save this file to any other known location on your local system for later installation.
• Double click on executable file to run the installer and this will launch a User Account Control dialog indicating confirmation if you want to allow this app to make changes to your device?

Detect older versions (8u20 and later versions). Starting with Java 8 Update 20 (8u20), on Windows systems, the Java Uninstall Tool is integrated with the installer to provide an option to remove older versions of Java from the system. The change is applicable to 32 bit and 64 bit Windows platforms. See an example dialog below. Depending upon requirement you can choose to Uninstall now or later. It is highly recommended to remove any unsecure older version though.

Notifications about disabled Java and restoring prompts

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 option for restoring the prompts. The installer may ask you to reboot your computer if you chose not to restart an internet browser when it prompted you to do so.

To test that Java is installed and working properly on your computer, run this test applet.

NOTE: You may need to restart (close and re-open) your browser to enable the Java installation in your browser.
