How do I watch video???

hi

in my app i added a file "dust.mp4"

when i run the app in the browser i see the video playing.
BUT when i compile it to NW.JS for windows, i launch the exe, and i dont see the video anymore, i just see the layers behind :s

i tried 20 times, nothing seems to work, when i export an app nwjs for windows with an mp4 inside, the video is not visible whe i run the EXE.
the video is visible and play well under browsers, but NOT when compiled in EXE

Please can someone TRY this, add a mp4 video in your test project, export to EXE and tell me if it works???
because from MY SIDE, NOTHING WORKS ( i use LAST update of construct2 steam)!!!!

Yes. Not working mp4.
