Installation of the fancybox module

Good day! I've been working on installing fancybox for the second day now, and no matter how I try to install it, it still says "fancyBox library not found. Please download the library and install it to sites/all/libraries/fancybox." I downloaded this library, but I don't understand how to install it. I unpacked it into the /modules/libraries/fancybox/ folder, but it doesn't work. I also tried following this tutorial http://xandeadx.ru/blog/drupal/142 , but that didn't help either.  Can anyone provide some guidance? Thank you!
