Purpose
You are troubleshooting the error "a process requires a Windows privilege which has not been granted".
Resolution
The most common cause of this error is when using the Run as Logged on User option in PDQ Deploy and the deployment user hasn't been granted the replace a process level token privilege. PDQ Deploy attempts to grant the privilege to the user but if it fails to do so this error will occur. Ensure that the required privilege has been assigned to the user and try again.
