Windows Assessment and Deployment Kit and add-ons are required to be installed with an administrator account. The UAC (User Account Control) should also be set to 'Never Notify'
Sometimes GPO's will also prevent an administrator account from installing either component.
Install the Windows ADK with a local or domain administrator. Also ensure that the UAC is disabled or set to 'Never Notify' for best results.
If issues still arise, then review the setup log files and contact Microsoft support.
