Setup cannot detect an SMTP

Hello
I got a problem. Windows 2008 R2 does not support Exchange (SP, SP1 and SP2) 2007, however since SP3 it is.
But my installation disk only has Exchange 2007 SP1, that’s why first I had to set up this iso and after that update it to SP3. What is the reason?
Help me. Please. Thanks.
Error: “Setup cannot detect an SMTP or Send connector with an address space of ‘*’.”
