From Nikon:
This is the Capture NX-D 1.0.1 software download - This is a update installer for Windows systems only.
Updates included with 1.0.1
- 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.
