Have you messed around with the UAC settings in Windows 8.1? (adjusted the slider or disabled)
Windows 8.1 will not allow a unsigned BETA driver install without you giving it permission to do so...
You state that you "never saw" such a prompt asking if you wanted to allow a unsigned driver install.
That would be completely incorrect, and is certainly why it hung when it did.
