Somebody knows where can I get the Nikon 200-500mm lens profile for Lightroom 6 (I do not have lightroom 6 cc) from the adobe website?, I have lightroom 6 ver 6.1.1 and camera raw ver 9.1.1
Lightroom 6 and Lightroom CC both have the same lens profiles available. I have Lightroom CC 2015.3, and there is a profile for the Nikon 200-500 mm lens. I don't know when that lens was added. But since you are a couple of updates behind that might be the problem. Also, be aware that lens profiles are designed specifically for a file format. So if you are shooting JPEG images with that lens and the profile is for raw images, it won't be available.
I just checked the link that you are given. The profile you are looking for was added in Lightroom 6.2. So you need to do an update in order to get the profile.
