What threw me off was the fact that they'd installed it in the "Photoshop Only" directory instead of the higher level File Formats directory, which is where I keep my Adobe Raw plugin.

Thank you, Sebastian, for your suggestions. It was great to learn about the "delete preferences" option.

Hopefully anyone else who's had this problem will see this thread.

Best regards,

Dear James,
I have Photoshop Elements 3.0. I recently bought a Nikon D80 and installed the software.
I have not been able to use Photoshop because a pop up says: Application has failed to start because NkNEFPlugin.dll was not found. Reinstalling this application may fix this problem. I searched for all plug-ins but only found Adobe Photoshop. If the plug-in cannot be found and I have removed Nikon's programs from my computer, then I am at a loss for what might solve the problem. I understand all the frustration that comes with this!
Any suggestions?

In need of help,
