Why, oh Why do people say "I can't install this app" without saying WHAT APP IT IS. Seriously, Im not trying to hate on you, but too many people say they have trouble without saying what they are trying to do.

You give the OS version, but not the app name. How can we give a step-by-step without all the information.

You can also get an internet connection via USB. You might want to look into that.
