Since I wanted to work on my Kindle Fire HD also own documents and by far (!) Best app is not to get it in the Amazon App Store, unfortunately, I was looking for a way that with my Windows PC and downloaded to the manufacturer Kindle transferred app to install. Easy Installer was my first attempt and an immediate hit. No study of complicated workarounds or modifications guarantee and warranty my Kindle had shot into the wind - just Easy Installer download, put desired app in the Documents folder and Easy Installer Start (previously of course temporarily installing apps from other sources in the Kindle Enable). Easy Installer finds all programs not yet installed and install them with a click. Convenient as it gets!
