After Lightroom CC updated to Lightroom CC-2015, and Camera Raw yesterday, both Acrobat X from my CS6 suite, and basic free adobe reader stopped working. Neither will start either by clicking on their respective icons, or from an adobe PDF file. Both were working
fine before the install of the update. I have not upgraded to the new Acrobat DC because I want to retain my CS6 license.
