Apartment Life won't install

[rosielee]

Please help me. I have Sims 2 Double Deluxe installed and I'm trying to install my new apartment life expansion pack but it doesn't complete. After I insert the CD I click Run autorun.exe, select English, click yes to the license agreement, click ok for the message that tells me not to uninstall, enter the registration code from the back of my instructions and click next. After that the screen just disappears and nothing else happens. It doesn't error and it doesn't install my expansion pack either. It just disappears. I've retried it about 5 times.

I'm using a laptop with Vista and it meets all the requirements. Thank you for your help!
