I downloaded the newest version of camera raw for LR. I have LR4 and can not import photos from my new Nikon D750. The download said it was sucessful but I still can not import photos.
you need cr 8.7 or better.
lr 4 cannot be updated to use 8.7.
you can either upgrade to lr 5, or use the dng converter.
Lightroom doesn't use the Camera Raw plug-in. So downloading the latest Camera Raw didn't do anything at all for you. The only way to update or upgrade Lightroom is to obtain the latest version. If you have Lightroom 4 then the last version of Lightroom you can have at no additional cost is Lightroom 4.4.1. If the camera you are using requires anything newer than what is supported and that version of Lightroom then it will require an upgrade to Lightroom 5.
