If you're using an USB bootable media to do an in-place upgrade or clean installation with the Windows 10 Fall Creators update, the installation may fail due to corrupted files on the installation media. How can you fix this problem?
Redownload the ISO file and recreate the USB bootable media again. If you're using the Media Creation Tool, use the Disk Cleanup tool and delete the Windows Setup temporary files before re-downloading the installation files, and then use the application to create a bootable media one more time. (If you skip the Disk Cleanup step, you're likely to see the same problem again.)
