I've been attempting to update my Lightroom via Creative Cloud for months. It keeps getting stuck at 50%. Since I don't have the latest version, I'm unable to open my NEF files in Lightroom. They will open in Photoshop though. If anyone has any suggestions, I'd greatly appreciate it.
Have you tried downloading the update installer from this website?
Click on Lightroom 6, and then choose the appropriate update according to your operating system. The update will take care of both Lightroom 6 and Lightroom CC.
Thanks!! Worked perfectly. I was on a similar site and couldn't find the actual download links.
