Solution Manager key

I apologize if this is the wrong forum or if this has been discussed already...

I just received SAP NetWeaver 7.0 SR3 through SDN. I do NOT have any other installation nor do I have access to an installation of Solution Manager.

When trying to install NetWeaver, it asks for a Solution Manager key. How am I supposed to generate this key???

Thanks for your help.
