Can't install/update Maps Pro from the Windows Store, error code 0x80073CF0
This is actually a bug of the Windows Store, not a Maps Pro bug.
The root cause of the problem is that Windows stores app downloads in the C:\Windows\SoftwareDistribution\DeliveryOptimization folder and in this case the app has only part downloaded and the file is invalid, re-trying download from the Store fails as it uses the cached file so you get the 0x80073CF0 error.
To solve the Windows Store 0x80073CF0 error, go to C:\Windows\SoftwareDistribution\ and remove the folders "Download" and "DeliveryOptimization".
