avast on 2 networked pc's

I have a small network at home, just 2 PC’s. I am using Avast v4.5 home edition on one of the PC’s and I want to load it on the other.

I assume I can use the same download but do I need another code? And, does the second code need to be sent to a different email address?

Thanks in anticipation.
