ReactOS Setup is an integral component that is part of the operating system responsible for the installation of ROS during 2nd installation stage. The situation with current master branch is like this -- the Services component always tries to create the process on behalf of the logged in user with its own security context. That user doesn't have the privileges and access rights like SYSTEM thus the Services component tries to create the process but it fails to do so because of lacking of required access right, TOKEN_DUPLICATE, in order for the calling thread to impersonate as self.
