c++ - Doxygen not outputting anything -

i'm trying document project doxygen , doxygen not create output anymore. first time ran doxygen via doxywizard, went fine, discovered graphviz not in path variable , none of dots worked. closed doxywizard, deleted output folder , contents, added grahviz path, , doxygen not output anything, using basic options (even without diagrams).

might missing something? here doxyfile used:

when run doxygen configuration, log shows nothing *** doxygen has finished printed immediately. working directory set same directory output directory i.e. e:/doxygen.

so further investigation seems though doxywizard having fit when tried using make.bat file in latex , exit without errors. able generate documentation via command line.

i'm not sure whether bug or result of incompetence , have overlooked something, considering worked once before without issue.
