SCCM Task Sequence

I am trying to deploy Remote Server Administration Tools as a part of task sequence when imaging a machine.  For some reason I can't get it to install.  I am attaching the script used to run please give me your thoughts:

REM ======================================================
 REM SET DISM Directory based on OS Architecture
 REM SET RSAT Version based on OS Architecture
 REM ======================================================

IF EXIST %WINDIR%\SysNative\dism.exe (
     set DISM=%WINDIR%\SysNative\dism.exe
     set RSAT=amd64fre_GRMRSATX_MSU
 ) ELSE (
     set DISM=%WINDIR%\System32\dism.exe
     set RSAT=x86fre_GRMRSAT_MSU
 )

REM ======================================================
 REM RUN WUSA to install RSAT
 REM ======================================================
   
RSAT-x64.msu /quiet

REM ======================================================
 REM RUN DISM to enable features
 REM ======================================================

%DISM% /online /enable-feature /featurename:RemoteServerAdministrationTools /featurename:RemoteServerAdministrationTools-Roles /quiet

REM ======================================================
 REM EXIT Errorlevel
 REM ======================================================

EXIT /b %errorlevel%
