SP2c is an OEM specific Service Pack which introduced a new Product
numbering scheme which cannot use prior keys but as far as I know that
is only supposed to apply to OEM versions, I'm not sure why you cannot

somebody else has a better answer, perhaps SP2c is now also used with
the newer retail versions?
