  1. Go to the Java download page.
  2. Download the JRE version 1.8.
  3. When the download has finished, run the Java installer. At one point, you will be asked to choose a directory to install to. Copy or write this directory down for use later.
  4. Check that the JAVA_HOME environment variable has been set correctly.
    1. Open the 'Start' menu, choose 'Run', type cmd in the 'Run' dialog box and click the 'OK' button.
    2. In the command prompt window, type echo %JAVA_HOME% and then press Enter.
    3. View the result:
    4. If a directory path is displayed that looks similar to one of the following examples, with the letters 'jre' immediately preceding a version number, and this path matches the location where you installed the Oracle JRE, then your Oracle JRE has been successfully installed and your JAVA_HOME environment variable has been set correctly. ''Examples of typical JAVA_HOME environment variable values'':

                      • c:\Program Files)\Java\jre1.8.0_20
                      • c:\Program Files(x86)\Java\jre7

    5. If nothing is displayed or you do not see 'jre' immediately followed by a version number (like one of the examples above), then you need to set the JAVA_HOME environment variable to the installation directory for the JRE. Please follow these instructions to set your JAVA_HOME environment to the directory where you have just installed the JRE. By default, this directory is under C:\Program Files\Java for a 32 bit Windows System. You will find it under c:\Program Files (x64) on a 64 bit Windows system.
