I bought VV2 for my PC and want to also have it on my laptop (mac). Is my registration code good for more than one install?

You will need to check with the company where you purchased your version of Virtual Villagers 2: The Lost Children. Some companies allow more than one installation. If you purchased the game from us, please note that we no longer provide activation codes, so you would need to contact me using the Support link in my signature so that we can re-activate your download link.
