Installing The Sims 2 Bon Voyage expansion pack

Question

I'm using a MacBook Pro running OSX. I have a copy of The Complete Sims, which is, of course, not complete. I ordered the Bon Voyage expansion pack and it won't let me install it because it says there is no software to install it into. Can you help me? I got an email saying that you can. Thank you.

I try to download sims 2 bon voyage on my laptop but it says i have 2 download sims 2 first but i dont know how can i have some help
