Lightroom 6.2 was running fine, until today when it spits out a box that says 'Error Code 16' and just ends abruptly. I am running OS X 10.11
What to do to fix?
I had already tried your suggestion and it didn't succeed.
However, this did fix the problem: sudo chmod -R 777 /Library/Application\ Support/Adobe
Now Lightroom 6 runs on OS 10.11 (El Capitan)
Glad to hear that the issue is resolved.
Thank you for sharing the resolution that helped you to fix the issue.
