    Help with error 0xC004C020!

    Where did you get the Windows 7 License from?

    https://support.microsoft.com/en-au/help/10738/windows-10-get-help-with-activation-errors

    Applies to: Windows 10Windows 7Windows 8.1

    [table][tr][td]0xC004C020[/td][td]This error occurs when a Volume License (a license that was bought from Microsoft by an organization to install Windows on multiple PCs) was used on more PCs than the Microsoft Software License Terms allow. To fix the problem, you might need to use a different product key to activate Windows on your PC. Contact your organization's support person for more info.[/td][/tr][/table]
