Can Nikon NX-D run on Windows XP – or can Photoshop CS5 work on Vista or later?
Chris says… Nikon’s new NX-D editing program unfortunately does not work on the Windows XP operating system. You need Windows Vista, or Windows 7 or 8. The full system requirements can be found at https://support.nikonusa.com/app/answers/ detail/a_id/19153/~/capture-nx-d-1.0.1---windows-only
The good news, however, is that it seems that your old copy of Photoshop CS5 will work with Windows Vista and Windows 7 (see the detail at http://www.adobe.com/store/ en_us/popup/software/photoshop5extended/systemreqs.html ).
So you can use NX-D to process RAW files, and then use CS5 for the creative stuff.
