I've installed Office 2007 for a customer's newly purchased PC with Office 2007 with the OPK Master Kit for OEM use.
I've used the product key from the customer's end user license/activation pack (the medialess license kit - MLK).
During the install an optional 'Referral Key' was requested, but I couldn't find a white sticker anywhere on the packaging.
Can someone explain what the Referral Key is for and where I can find it?
Thanks
Shawn
