The problem is under the Windows 10 ISO under the Sources folder, there is a file called install.wim. Finally I decided to push through manually and it worked. However this error occurred over and over. I verified the system was fully ready to install. I’m installing on a MacBook Pro 15 (2016).
I ran into this issue trying to install the full version of Windows 10 Pro October 2018 using 10.13.1 Mojave. Continued Conversation from Boot Camp error: An error occurred while copying the Windows installation files
