I downloaded the Picture Project 1.6.1 installation Zip file (PP161.zip) from the Nikon website. I can unzip the file OK but when I click on Welcome.exe, which is what Nikon says to do) I get a window with a red X and an OK button. When I click on the OK button the window disappears and nothing happens. I downloaded the file a second time, thinking it might have been screwed up, with same result. I don't know that I need V1.6.1 with my D50 but would like to have the latest version. Any inputs will be appreciated.
