How to install copy of expansion pack on original sims 3 game?

Can I install copy of expansion pack to original sims 3 base game. And if I can, can you tell me how. I want to install generations, seasons and university life.

yes when you download the expansion you can find in the file a file called:
# Installation Guide

This will guide you
E.g. -> Seasons guide

The Sims 3: Seasons - Installation Guide



1. Open the 'Sims3EP08Setup.exe' and follow on screen instructions.
2. When a serial code is needed, use one of the following codes:

8YTK-KEEQ-QDNT-P3ST-CS7X
3Q9Z-J8UM-EMME-6XAA-VK83


3. After the installation finished, open the "# Crack" folder in this .rar file and
drag & drop (or copy) the "TSW.exe" and the "TSLHost.dll" file in there to exactly:
C:\Program Files (x86)\Electronic Arts\The Sims 3\Game\Bin (SO NOT THE EXPANSION'S INSTALLATION
FOLDER, BUT THE BASE GAME'S INSTALLATION FOLDER INSTEAD!!!)

5. Start the game and... ENJOY playing!

Hello,

Sorry for the late reply!
Unfortunately we were not able to get back to you in time. I'd like to apologize for that.

Do you still need assistance?

I already install the game, thanks anyway.
