From the Nikon UK website:
Capture NX-D is development processing software that realizes the full potential of the camera and lens to produce images captured by a Nikon digital camera of the quality envisioned by Nikon's developers. Designed specifically for processing RAW images, Capture NX-D offers responsive and intuitive controls. In addition, characteristics such as brightness, contrast, and tone curves of not only RAW images, but also JPEG and TIFF images captured with Nikon digital cameras, can also be adjusted.
Please note, when this software is installed under a 64-bit operating system, Capture NX-D Ver. 1.0.1 (for 64-bit operating systems) will be installed.

Modifications enabled in this version
When the 64-bit Windows version of the application was used to create JPEG-format files converted from RAW (.NEF/.NRW), TIFF, or JPEG images using the Convert Files... or Run Batch Process... option in the File menu, a gray band was sometimes visible at the bottom of the images when they were opened in the 64-bit Windows version of Capture NX-D. This issue has been resolved.
