I use Multisim V7, where can I download comp. models/propert

I use Multisim V7 and I have built a circuit on a board, now I want to simulate it, but the transistors and other components that I'm using are not in the multisim components list and I don't know how to add the properties of the transistors in multisim V7.

I know there is a webpage to download models/properties of components for Pspice. Is there one for multisim V7.

Thank you

Multisim 7

Update for multisim 7 is no longer available. You can download the
datasheet of the component you posses and manually edit the component in the program...
