I was working for the past few days with ViewNX vers. 2.10.3 64bit doing basic edits on NEF+JPEG files and it stopped working on a new folder of images. It says 'unsupported file type' every time I try to do an edit to these NEF+JPEG files - shot with a Nikon D7100 and transferred over to my computer with Nikon Transfer. If I turn off View NEF+JPEG files, then both show up in ViewNx but only the jpeg will respond, the NEF still gets the 'unsupported file type'!! NX2 opens it as a black window with 'updating image' at the top while listing as 27.3MB in size so it's also useless unless I can get the NEF to open. I reported this in the past and support told me NX2 will not work in Windows 10, don't believe it, and to use Capture NX-D which after hours I found out that it does not do a file save to make a JPEG which will be the end result of my project. Besides Capture NX-D doesn't open the NEFs in this folder either. I going to try using Nikon transfer again to make NEFs in a new folder or maybe convert them to Jpegs but I much rather have all the data to work with. I would try to post one but the forum will not take NEF files, I'm attaching my file data if that could be of any helpView attachment Shootingdata1.txt. Any suggestions on how to get these NEFs working again???
