You're post is not showing the error message. Should it have been in the gap between paragraphs? As we speak I'm upgrading out fifth machine. I've done those upgrades with the Windows 10 Upgrade Assistant provided by Microsoft. The program is Windows10upgrade28084.exe which appears to be exactly what you're using.
Thanks for the information. I uninstalled the graphics driver provided by Dell and then installed the driver from Intel. Upgrade worked perfect.
