I've trying to install media9 package, but I continue to get the error:

pdflatex> ! LaTeX error: File 'media9.sty' not found

I tried all that was suggested for *.sty file not found, but I just can't even see the media9 package on the package manager (even logged as administrator), nor to obtain any answer when I write in the command window findtexmf media9.sty

I'm using TeXnicCenter 2.0 and MikTeX 2.9.

You should see package media9 in the MiKTeX Package Manager. If not there could be a problem with the internet connection or you have a problem with your installation. Have you tried a reboot? – Kurt Apr 8 '13 at 12:48

If it is not in the MiKTeX package manager, try a Synchronize Package Database (or similar) first.

Thanks, it worked perfectly. Do you have any idea why this happens? I tried refreshing FNBD and didn't work – Mario S. E. Apr 8 '13 at 12:52
It is a feature of MiKTeX. The package database and the packages themselves need to be updated separately from time to time. If you don't update the database you will miss out on new packages on CTAN and in the MiKTeX repositories. – AlexG Apr 8 '13 at 12:59
