Do you have Graphviz installed and on your PATH?

Go into a command line window and try
dot -V

You should see a result like this:
dot - graphviz version 2.36.0 (20140111.2315)

If you have installed Graphviz and don't want it on your PATH for some reason, you can still explicitly specify the path to the dot executable in your Doxygen config file.

See

I'm getting the same error, I have set the env path, have set the dot path in the doxygen DOT PATH.
CMD "dot -V" output: dot - graphviz version 2.38.0 (20140413.2041)
I tried all the recommends all over stackoverflow and other forums.
BUT THE FIX WAS JUST TO RESTART ECLIPSE.
I GUESS ECLIPSE DOES NOT GET THE UPDATED INFORMATION LIKE SYSTEM PATH UNTIL AFTER A RESTART.
