The command line instruction options (i.e., s, v, q, etc.)  used  for the Control Expert silent install is case sensitive.  If the command line options consists of upper case characters  (i.e.,   D:\Setup.exe /S /V /QN INIFILEPATH=C:\Installers\EcoStruxure\CE_SilentConfig.in   ) the instruction will fail to run.

To resolve the issue, ensure that the command line instruction uses the correct syntax and character case as shown in the help.
