If you still have the registration key that was emailed to you, re-enter that. If you have lost it, re-register avast! 4 Home Registration you will be sent a new key.
You don’t need to save it and paste it anywhere, just do a manual update or download this avast! VPS Update - Manual Download and run that it will update the iAVS.
You could also download the latest version of avast! if you have done a number of program updates since you first installed it.
