Pushing new Acrobat DC failing

All,

PLease let me know if you have any idea, we are trying to replace acrobat X with Acrobat DC by using the following bat file. but when it runs it only rips out acrobat x and never installs acrobat DC.

@echo off

echo.
echo Uninstalling Acrobat X

msiexec.exe /x {*license*} /qn /NORESTART

echo.
echo Installing Acrobat DC

msiexec.exe /i "%~dp0AcroPro.msi" /t "%~dp0AcroPro.mst" /qn /norestart

"%~dp0AdobeSerialization.exe"

IF %ERRORLEVEL% NEQ 0 GOTO END

:END
echo.
echo Install Finished
echo %ERRORLEVEL%

Any advice would be appreciated.

Regards, Mike
