How to Import & Install Furniture Library?

[NavinTalati]

friend, I need your guidance. I have my WIN-7 as OS. SweetHome3D is successfully installed and also working nicely. I need more models of furniture and other things readily installed and available through the menu bar of this software.
1. I downloaded few of concerned files and double clicked. But could not be installed.
2. I also tried the route thjrough menu-bar as: furniture > Import Furniture Library. But could not be installed.
Please guide me HOW TO GET SUCCESS in this matter? Am I missing something?

You have to install the SH3F files inside the ZIP files available for download.
