Windows cannot read the <Product Key> from the unattend start file"

[lattice0]

I get stuck at

==> virtualbox-iso: Waiting for WinRM to become available...

then opening the VM on virtual box I see:

When I open Windows cannot read the <Product Key> from the unattend start file"

I had to do this:

            <UserData>
                <ProductKey><Key/></ProductKey>
                <AcceptEula>true</AcceptEula>
                <FullName>Packer</FullName>
                <Organization>Packer</Organization>
            </UserData>
