How do I activate the same copy of TurboTax on multiple computers (one connected to the internet and one not connected)?

I have a standalone computer that I use to prepare my return, however TurboiTax requires either a connection to the internet or phone call to activate it. I have another internet connected computer which I use to file the return but it also requires an activation code to work. Using the same copy of TurboTax what is the easiest way to receive the activation codes and transfer them between computers?
