ARCHIVE - Install or revert to a prior version of Java - Mac OS X **Voyant Adviser, UK and Ireland**

Reverting to a previous version of Java following an update is a three-step process. You will first uninstall Java, then download and install the older version of Java from the Oracle archive, and then reinstall Voyant.

Before you begin: To uninstall Java, you must have Administrator privileges and execute the remove command.
