What can cause "Service exited with abnormal code: 1"?

I have tried uninstalling and reinstalling. checking permissions. uninstalling other apps reinstalling OSX etc etc etc and still I cannot run zbrush 4r7. 4r6 and every other app runs fine.

If I had a clue as to what MIGHT be different between 4r6 and 4r7 as to what might be causing a conflict, I might then find out where the problem is.

By the way I am on osx 10.10.2

No idea if this is related
