I installed Capture NX 2.3 on my apple computer. Now when I click on a JPG I get the following error message: "Cannot load file: Macintosh HD/Users/Dennis/Pictures/Africa Day 2/20110617_Africa days2-3_0382.JPG Invalid color format. The file format is not supported." This is what I get no matter what JPG I try to open. I have uninstalled and reinstalled but to no avail. I have ask for help from Nikon and I am awaiting a second answer the first was the above action. I am hoping somebody, here had an answer.
Let's break it into separate steps to find out where the problem is.
Can you open the JPEG file using any other program on your computer? JPEG images are pretty generic - they should open on most computers with a wide range of programs. This will confirm the file is not corrupted.
Can you simply open the program Nikon Capture NX2 version 2.3? Can you verify that it is the right version?
Can you open the folder list and browser on the left side of the Capture NX2 screen?
When you open the browser, what happens? Do you see thumbnails?
well, if you have the NX2 icon on your dock, you right click it and select 'show in finder' - then you right click that icon and select 'show info' - near the top of that display panel should be a check mark box that says 'open in 32-bit mode' - just check the box and close the panel; then start NX2...
click on applications folder and click 'open in finder' - proceed as above in finding NX2. app ...
click finder on the dock and then file/new finder window and there navigate to your NX2.app and go as above
Anyways, once you find the application you just right click on its icon and check the box for 'open in 32 bit mode' in the resulting info panel!
Hope that was confusing enough - but there is usually more than one way to 'skin a cat'...
I was wondering about that too - the fact in my case is however that NX2 would not display ANY jpegs that were already on my hard drive until I went into 32 bit mode ( jpegs from Nikon, Olympus, and Canon) - they all came up with the same error message. They showed in the 'filmstrip' but would not display (open in the edit window) ...
I am having the same problem and I am running 10.7.2 and yes I am running in 64 bit mode. Interestingly, if I use NX2 to save a jpg from a nef, I have no problem opening the resulting jpg file in NX2. Also if I use Photo Mechanic to save a jpg file as a TIF, again no problem opening the file in NX2.
