Hi Toni Chappell,
You currently can't officially install the Amazon Alexa app on a Windows 11 PC. The application was previously a native Windows software package distributed directly through the Microsoft Store and Amazon officially discontinued this dedicated desktop client and removed its distribution package from the active store repository.
If you try to force an installation using old links, the operating system will reject the request because the official AppxBundle installation files are no longer hosted or digitally signed by the developer. You must also actively avoid downloading standalone executables from unofficial websites. To utilize Alexa services moving forward, you will need to rely on the official applications available for iOS and Android mobile devices or use dedicated Amazon hardware.
Hope this answer brought you some useful information. If it did, please hit “accept answer”. Should you have any questions, feel free to leave a comment.
