Licensed CCleaner professional yesterday for three computers put key into my wife's computer took key but would not recognise my name can you please help
You have to use the exact same name that you used when purchasing the licence.
(If you are copy/pasting it from the confirmation email then check that there is no leading or trailing space being copied).
Also if you have registered the licence in your name but are trying to put your partners name in for her machine then it won't accept it.
This gives more info about registering and possible problems:
