In order to install the plug-in onto your computer, you need to download a version that is developed for Mac OS. You can't use this version on your computer because this is compatible only with Windows platforms. A compatible version for Mac is available on the official website. The plug-in can only be used on Photoshop CS2 or Photoshop CS3. Because of this, there are little chances that you can use it on Photoshop CC.
