Can't install Accordion Menu

Hello,

At First! Sorry for my bad english.

I can't install the accordion menu on my joomla 3.4.0 system.
When click the upload and install buttons appears the error message:

JInstaller:: Install: The Joomla -XML installation file could not be found.
Can not install package to be found!

Where is the problem? Can you help me?

Thanks,
fireb
