NOTE: The formatting of the license files is different in the 5.7 and 5.8/5.9 versions of Defender. If you do not have the correct type, you will need to request a new license from the
Licensing department, or from your account representative. You can tell the difference by examining the contents of the files in Notepad. A 5.7 style license, will say "Quest Software" and will have an encrypted "DATA" string at the end.
3. Click "OK" once you have entered a valid
License key and
Site message.
4. Then click "Done" to close the "About" dialog window.
