Update to Avast 2014 from EPP 8.0.1490

Hi, I manage my Avast pool of client from Avast Enpoint Protection Suite 8.0.1490. The update tool says I have the last update.
How can I update to Avast 2014 ? I have some new PC with windows 8.1 installed that seems to don’t support avast 8.

thanks

Right now you can’t. (See: http://forum.avast.com/index.php?topic=139258.0)
