can't install amazon app store on Galaxy S5 (app could not be installed)

I've enabled "Unknown sources" , no screen filter , i have Lollipop , debug mode on , and every time i hit instal after some seconds it shows me app could not be installed !!!
i can install other apps not included in the app store but fail only on the amazon app store.
