    Try resetting Windows Update components then upgrade.

    Ztruker, thanks for the advice but after running that tool it told me the service regestry was missing or corupted but it didn't fix my issue, the installer still stops around 20% of the way through the second step.

    I attempted to install the 32-bit version of windows 10 just to see if that was having the same issue and that worked fine although it wasn't activated, the installation completed and booted up so it's a problem specific to the 64-bit version. hopefully that will give you a better idea of what might be causing it.

    Has anyone solved this issue? I have tried doing a clean install multiple times on a new drive and get this error. I have started with a clean drive, a cloned drive of my current W10 Pro 32 bit drive and nothing changes. Does anyone have any idea why this happens?

    How are you trying to do the install?

    MediaCreationTool, immediate update.
    MediaCreationTool, create a flash drive, boot and install?
    MediaCreationTool, create an ISO then burn a DVD or create a flash drive to boot and install from.
    Via Windows Update.

    The error you are getting is usually caused by corrupted or damaged install media.

    i'm using the media creation tool to make a flash drive for the install and i had completely uninstalled my antivirus softwear so i can't imagine that would be causing issues.

    If you are doing a clean install, what is currently installed on your computer doesn't matter since you will be formatting the boot drive.

    See here: Windows 10 - Clean Install

    For best (and safest) results, disconnect any other hard drives during the install. Reconnect after the install has completed.
    Also disconnect everything from the computer except mouse, keyboard and display, EVERYTHING!!!
