Why won't apps downloaded from the Amazon App Store install (Galaxy s4 4.4.2)?

[AC Question]

Apps downloaded from Amazon App Store won't install (Galaxy s4; 4.4.2)

Trying to install an app I've downloaded from Amazon App Store app but keep getting the message "App not installed". I have removed all other android devices from the My Devices list on the desktop Amazon App Store and reinstalled the app on my phone with no success. Unknown sources has been allowed in settings

Please help.
