    Once the variable is opened, a text box in yet another window appears.Careful not to delete anything in this box. At the end of the text box, add a semi-colon if there is not one already, and add "C:\Program Files\Java\jdk1.6.0\bin" to the text box. This is assuming you did not change the file path of the installation.
