I purchased Tropico 4 and Modern Times from Amazon and Tropico 4 installed fine but I don't know how to install Modern Times.

It just gave me a key to enter but I don't see anywhere to enter a key when I go in the game.

Can someone help me?

EDIT: I have the PC Version installed on Windows 7.

EDIT: I have it all figured out. I actually had to go into my registry and find entries where it was blocked from going online. I don't know why it was blocked that way. But now everything is installed.

Thanks!
