In app update can fail if a newer version of the app has been released since the last time the app was opened

If the user has “BETA023”, they load the app and there is a new version “BETA024” it will display the “New Update Available” message in the windows titlebar. If the user does not update the app or close the app. Then a new version “BETA025” is released. The user then clicks the update button and starts the download, the downloaded binary will be “BETA025” but the hash remains the one that was from the app’s initial loading “BETA024”.

It might be resolved by downloading the version info immediately after the binary download is complete, and then comparing the hash of the binary to the fresh version info hash.
