Thanks to vern for the link that gave me the answer. This is from Nikon's
website;We plan to make a Windows Vista-compatible version of PictureProject, for
use with the following models, available for download. Both the PTP and Mass
storage USB transfer options can be used for camera connection.
D2XS, D2HS, D2X, D2H, D200, D100, D80, D70, D70S, D50, D40
We also plan to make D40 firmware, œCertified for Windows Vista, available
for download.
We do not plan to offer compatibility for D1-series cameras (D1X, D1H, D1)
connected to a computer with Windows Vista preinstalled. Use a card reader
or card slot to transfer images. <<<<<<<
