The Viki app on the Xbox 360 console is no longer supported, as of January 12, 2017.
This is due to Microsoft's decision to no longer accept updates from developers on the Xbox 360 apps, and companies worldwide, including us, will be unable to update, fix and support this device.
As of today, no fixes are expected on the platform and the app will no longer be available for download on the Xbox 360 app store.
We hope you understand that this is a Microsoft decision, and not a Viki one. We can recommend you other options to watch Viki from your TV, such as Chromecast, Roku, Apple TV, or using a HDMI cable. For more information, you can refer to viki.com/apps for a list of TVs and devices that we do provide full support to.
