Using Creative Cloud on OS X 10.11, Lightroom CC 2015.3 and Photoshop CC 2015.1.1.
When in Lightroom Library - Photo - Edit in Photoshop… often results in error dialog. See attached screen shot. Sometimes, but not always, quitting PS and restarting it resolves the issue. This happens 50 - 75% of the time I try to 'edit in Photoshop' from Lightroom.
Any thoughts would be appreciated.
Most of the times it is an issue with the permissions over adobe folders.
I would suggest you to reinstall Lightroom and Photoshop from a new user account(admin rights)
