Hmmmm downloading the OPK. I don't like the sound of that. Typically Microsoft mails you the OPK... They come in big yellow envelopes... If you are not a Microsoft Partner in the OEM Channel, it is not legal for you to use the OPK Tools. You need to use the WAIK. If you are in the OEM Channel, you need to contact your TAM on documentation to use the OPK Tools, however this information is also on the Extranet.
