c++ - Matlab engine 2014a won't start under Windows 7 64 bit - missing a 2013a dll -

i can't start matlab engine using matlab 2014a, win7 64bit, 64bit build c++ programme using vs2012 or vs2013, intel compiler. can start engine fine using matlab 2013a. if link against 2014a programme complains libmwmfl_scalar.dll missing , won't start. dll included 2013 seems no longer included in 2014a (either in programme or in compiler runtime distribution). if link against 2013a runs no problems. why insist on old dll when update 2014a? i've changed includes, libs, environment 2014a , rebuilt after clean. have no explicit reference libmwmfl_scalar.dll in properties , have changed folders 2014a. i'm not linking else uses matlab. dll doesn't show if run dependency walker on linked executable.

the settings in property sheet post (call matlab straight (multiple threading) in visual studio) provides relevant context.

ben - no i'm not using mex files. code calls matlab

here path, both 2013a , 2014a present. i've tried removing 2013a, relaunching vs, rebuilding still looks old dll.

update: tried creating new solution , project in vs2013 , works ml2014a. must affecting existing project or solution it's hard track downwards since have no indirect dependencies matlab , have set paths 2014a version. programme uses external libs boost, intel mkl, armadillo, eigen, quantlib. totally stumped.

update 2: i've checked , programme runs when linked against 2014a outside visual studio environment. when seek run vs debugging purposes ("debug/start debugging" or "debug/start without debugging") wont' run because of missing libmwmfl_scalar.dll. reason vs insists on run programme when programme doesn't utilize it.
