Important: The most recent Authoring tool comes with embedded Java. This means that you no longer need to change your Java settings on your computer. You can download it from the LifeGuide Community Server here: https://www.lifeguideonline.org/releases/authoring

The following advice applies to older version of the LifeGuide Authoring Tool ONLY

The LifeGuide Toolbox requires Java Version 6 or Version 7, 32-bit. The version of Java does not relate to the version of Windows that you are using, so if you have Windows 64-bit, you can still use the 32-bit version of Java.

Modern versions of Windows and computers managed by an IT team may automatically update your Java to Java 8.

This guide helps you to identify your java version and replace it with a compatible version.

After you have done this, you will need to close and reopen the Lifeguide Toolbox.

To check which version of Java you have on Windows 8/10:

Method 1: Uninstall tool

  1. Download and Run the Java uninstall tool:
    https://java.com/en/download/help/uninstall_java.xml
  2. Select Next until you reach the page which reports your Java versions:

      64-Bit Server VM
    • This means Java version 7 update 79 64-bit.
  5. If the Java version is greater than 7 (any update) OR says 64-bit, you will need to install a different version of Java.
    Java version command line

Method 3: Control panel
