Start Oxygen XML Editor and open the Help > About dialog box. Go to the
System properties tab and look for the
java.runtime.name and java.home
properties. Keep their values for later use.
Download the JAI Image I/O kit corresponding to
your operating system and Java distribution (found in the
java.runtime.name property).
Note that the JAI API is not the same thing as JAI Image I/O. Make sure you have
installed the latter.
Run the installer. When the installation wizard displays the Choose Destination
Location page, fill-in the Destination Folder field with the value of the
java.home property. Continue with the installation procedure
and follow the on-screen instructions.
