Target the installer for the Photoshop CC Plug-ins folder. If the installer asks if you are installing the 32-bit or the 64-bit plug-in, select the 64-bit plug-in. Or if you have already installed Invigorator for Photoshop CS6, you can simply move the plug-in from the Photoshop CS6 Plug-ins folder and placing it into the Photoshop CC Plug-ins folder.
Hope this helps. If you have any questions or are still having problems, please let me know.
