c++ - Application deployment doesn't work after adding QSound -

i have application deploy on other machines (visual studio). added module qtmultimedia use qsound class.

wanting redeploy app, executable indicates me first need qt5multimedia.dll qt5network.dll (which have not added in project).

now application doesn't launch, no error message, not understand ... did not find on internet.

first of - use dependency walker list dependencies , make sure have required dlls right besides binary.

next, make sure you've copied required plugins appropriate plugin folder besides binary. in particulary take @ plugins/audio/qtaudio_windows.dll, think might need deploy it.

also way check app uses use process explorer on machine have no troubles on check dlls uses when app running.
