Thanks, I found everything, it's very simple. I'm so sorry, but I really did not read the guide because I do not know English well, but reading the guide translated by google is not easy (easier to learn English! [:)] ) ..... then, I thought the Program is so simple that everything is clear .....
Then the way for uninstall the library is:
About (sweet home dialog box) – Libreries in use – if we click on the sh3f file open the furniture folder (user - application data- sweet home-furniture) - remove the file from the furniture folder.

Best regards
