is this where you are trying to get the conversion ?
- avast! 5 Pro license convert from 4.8 Pro license. Try http://www.avast.com/resend-license.php now, fill in the form giving your email and 4.8 Pro License key and they will send the new license file to you (presumably it will check you have a legit 4.8 Pro license first).
Thought this mentions an avast5 pro license that should work with avast 6.
Or contact sales (at) avast (dot) com, giving your information.
