Exchange CU7 Setup Error in RCPoverTCP

I am running Exchange Server 2013 CU6 on Windows Server 2012 R2.   I was running the CU7 update/setup, when it stopped with the following error:

Error:
The following error was generated when "$error.Clear(); 
          . "$RoleInstallPath\Scripts\ConfigureNetworkProtocolParameters.ps1"; 
          Enable-RpcOverTcpPortScaling; 
          Enable-ExtendedTcpPortRange
        " was run: "System.UnauthorizedAccessException: Access is denied ---> System.ComponentModel.Win32Exception: Access is denied

Any ideas on how to resolve this?  Thank you.
