Unfortunately, it is not possible to make AirServer Windows 10 Edition available on all user accounts when installing/downloading it from the Windows Store. 

At this time, the only way to do this is to download it again from the Windows Store on each user account. 

Some remarks:

  • There is no need to log in with a Microsoft account to get the app. If the login window appears, you can just close it again and the app will still download.
  • If the app was already activated, the activation will be shared between user accounts - regardless of it being downloaded from the Store again.
