Question

How to install multiple versions of Java on a workstation?

Cause

Workstation applications may require different versions of Java.

Answer

Multiple versions of Java can be installed on a workstation. Visit the links below and accept the standard defaults for installing.

The most recent Java version can be downloaded from: http://java.com/en/download/index.jsp

Older versions of Java can downloaded from the Oracle Java archive page: http://www.oracle.com/technetwork/java/archive-139210.html

When multiple versions of Java are installed the last version installed will be the primary version used unless the application calls for a specific version. If you are unsure which version of Java was installed last view the program and features on your workstation.

For Windows 7: In the start menu click on control panel select programs and features.

If your application requires Java 6 or 7, uninstall Java 6 or 7. Download the most recent version of Java 8. Then go to the Java archive page and download Java 6 or 7.

To view the versions of Java Runtime Environment installed on the workstation start the Java Control Panel. In the Windows start menu select run and type: javaws –viewer
