I am trying to install the MDT 2010 Toolkit but on the “Installing Microsoft Deployment Toolkit 2010” screen I get the error:

Error writing to file C:\Program Files\Microsoft Deployment Toolkit\Templates\Distribution\Scripts\Autorun.inf. Verify that you have access to that directory.


Make sure you are not running an anti-virus program that is blocking the creation of Autorun.inf which was the problem in this case. Stopping the “McAfee McShield” service then clicking “Retry” allowed the installation to complete successfully at which point the “McAfee McShield” service was restarted.
