Learn how to install objects for Sims 1 with this tutorial.

The Tutorial
  1. Step One: Save the File to Your Desktop
    Click on the download link or button and save the file to your  hard drive.
  2. Step Two: Extract File if in Archive Format

    Browse to The Sims folder on your system.
  5. Step Four: Place .IFF Inside of “Downloads” Folder
    Inside The Sims directory, there is a folder marked “Downloads.” Place the .IFF file in there.

Voila! That’s it! The next time you open your game, go into the Build or Buy Mode catalog and you should see the object you just downloaded there.
