Java - Downgrading Java (Windows and Mac)

Customers are reporting that latest Java from Oracle does not work or has too many issues. This document will show you how to downgrade your Java from a new version to a previous version of Java.

If you don't have or think you may not have administrator access to your computer you may need to contact your local IT group for assistance with downgrading your Java.  Your local IT Professional will have older versions of Java ready to deploy either automatically or manually.

To Manually downgrade your Java version use the following steps:

  1. Open your Windows Control Panel.  Use this link to learn how to open your Control Panel .
  2. Open Programs or Programs and Features depending on your view.
  3. Select Java from the list of installed programs.
  4. Right click on Java and select Uninstall.  Java will then automatically uninstall.

    Mac: jre-8u###-macosx-x64.dmg
