Failure to install kodi on firestick

I just attempted to install Kodi on a firestick(fully updated), and every way I know has failed. I first used the app apps2fire, which is how i loaded on another stick that i currently have. It uploaded the apk but failed to initialize the installer. I’ve rebooted the stick an tried again, same result. Checked to make sure unknown sources where allowed, as well as the debug was turned on. Attempted a third try same result. Moved on to ES file explorer, which I’ve used successfully in the past and browsed to the external storage under the local link to go to the download folder and the apk is there, so I tried to install from there. The installer starts, I accept the permissions and proceeded to run the installer. It runs then fails about to the end of the process. Did this three times as well and rebooted the stick once after the first failed attempt. I then created a bookmark in ES to the Kodi download page and downloaded the file there. Tried to run installer and same result install failed. Anyone got an idea on any other method to try or how to get it to finish using the methods I mentioned. All help is greatly appreciated.
