Important: The first step of the procedure below instructs you to delete old directories/files before proceeding with the upgrade. It is recommended that you make a backup of these directories/files before deleting them. Make sure you make a backup of the licensekey.txt file since you will need the information contained in this file later in the upgrading procedure.

To upgrade your version of the Oxygen XML WebHelp Classic plugin for DocBook, follow these steps:

  1. Navigate to your DocBook XSL directory directory and delete the old Oxygen XML WebHelp Classic plugin files (oxygen_custom.xsl, oxygen_custom_html.xsl) and directory (com.oxygenxml.webhelp.classic).
  2. Go to Oxygen XML WebHelp Classic plugin website, download the latest DocBook version of the installation kit, and unzip it in your DocBook XSL directory.
    The DocBook XSL directory should now contain a new subdirectory named com.oxygenxml.webhelp.classic and two new files, oxygen_custom.xsl and oxygen_custom_html.xsl.
  3. Open the [DocBook XSL directory]\com.oxygenxml.webhelp.classic directory, create a file called licensekey.txt, and copy your license key that you purchased for your Oxygen XML WebHelp Classic plugin.
