Step-by-step
Before you start
Have your device connected to the internet and use only the app and account information confirmed for your setup.
Check your device
Connect your Fire TV to the internet and confirm that your model and software are supported.
Install Downloader
Find Downloader in the Amazon Appstore and install it. Do not install lookalike apps from untrusted sources.
Review app-install settings
If the supplied setup requires an APK, follow the device-specific instructions to permit Downloader to install that file. Do not disable security protections more broadly than necessary.
Use the supplied app details
Open the official app link shared with you by support, install the player, then enter the account details provided for your setup. Keep those details private.
