I am compiling this example from example link

documentclass{beamer}

usepackage{media9}



begin{document}



begin{frame}{dumb frame}

dots

end{frame}



begin{frame}{frame with sound includemedia[

  label=my_sound,

  width=1ex, height=1ex, transparent,

  activate=pageopen, deactivate=onclick,

  addresource=sound_sample.mp3,

  flashvars={

    source=sound_sample.mp3

   &autoPlay=true

   &hideBar=true

  },

]{}{APlayer.swf}}

dots

end{frame}



begin{frame}{other frame}

dots

end{frame}



pdfpageattr{/AA <</O <</S/JavaScript/JS (annotRM['my_sound'].activated=false;)>> >>}

I am using Win7 64bit, Miktex 2.9 TeXworks with pdfLaTex compilation. I keep getting this error

("C:Program FilesMiKTeX

The log file is saved here (as it exceeded the word limit in the question)

I can successfully embed wav file using package multimedia using code

begin{center}

movie[label=show,

start=0s,height = 0cm,width = 6cm, showcontrols]{}{media/specific-information-1-of-3.wav} 

end{center}

vspace{0.2cm}

begin{center}

hyperlinkmovie[play]{show}{beamerbutton{play}}

hyperlinkmovie[pause]{show}{beamerbutton{pause}}

hyperlinkmovie[resume]{show}{beamerbutton{resume}}

hyperlinkmovie[stop]{show}{beamerbutton{stop}}

end{center}

But package Media9 never worked and it kept showing the above error message.
Thank you.

Hopefully I am not misusing the space for further question again.
It is working now. I updated the following packages (though I am sure different settings should require updating different packages)

l3kernel

beamer

media9

l3packages

etoolbox

Thanks, @samcarter @AlexG @Phelype Oleinik and everyone else offerred suggestions. I learned a lot through the process.
