We are running into an issue were one of our Windows 10 machines cannot package any of the platforms (We tried Windows, Android and Linux). Instead, it launches a web browser each time you select File->Package Project->{Platform Name} and spams the output log with something similar to:
LogWindows: LaunchURL http://udn.unrealengine.com/docs/ue4/INT/index.html
From what I have read, there may be an issue with the Windows registry or Environment variables having incorrect values setup. How can I validate that things are setup correctly?
Note that this build is a source build and that the machine has had older versions of Unreal installed.
