Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Nikon Transfer may be downloaded, to install (on either Windows PCs or Apple computers) here:
If you need to change your system configuration (in a minor aspect of it) so that Nikon Transfer opens automatically when your camera is connected to your computer, rather than Nikon Capture NX-D, just let me know what computer you have (Windows, or Apple, and what version of Windows or MAC OS X is on it) and I will advise you how to do that (or if you want, remote-control your computer if it is a Windows PC, and do it for you, once you have installed Nikon Transfer.)
If Nikon Transfer is already installed on your computer, then I can help you configure it to open automatically in that case, too, I think.
Let me know, please. Thanks.
