Huge bummer here, folks. There is an issue where some cannot download the Tobii Experience app from Microsoft Store.
Something unexpected happened
This error is most likely happening because you didn’t get the driver via Windows Update yet so try installing it manually.
For Tobii Eye Tracker 5
Download the driver here
For all other devices
Please visit your manufacturer’s driver page.
For any other errors
Try resetting Microsoft Store by opening up your start menu, type in wsreset, and then press enter.
Then you can try installing the Tobii Experience app in Microsoft Store again.
