Personally my luck with the auto install has been pretty bad. Now that is not because AMD is doing something wrong. I have found that security software added will interfere with this installation and in this past year even Windows 10 update will mess it up.
If you want to have a more trouble free experience just let the Radeon Software notify you of driver updates. Then go get the driver package manually. I highly suggest loading them after a restart, with all security software temporarily disable and with the INTERNET disconnected so Windows update can't mess it up.
