Lorsqu'un chemin de configuration personnalisé est défini lors de l'installation, il est écrit dans le fichier ConfigurationSetup.cfg. Cette opération définit le répertoire racine de configuration dans la variable de configuration _USTN_CUSTOM_CONFIGURATION. Le msconfig.cfg inclut le ConfigurationSetup.cfg comme suit :

%if exists ($(_USTN_INSTALLED_CONFIGURATION)ConfigurationSetup.cfg)
%  include $(_USTN_INSTALLED_CONFIGURATION)ConfigurationSetup.cfg
%endif

Et voici le contenu du ConfigurationSetup.cfg, tel que fourni :

#----------------------------------------------------------------------
#  ConfigurationSetup.cfg - Configures the root Configuration directory
#  for Your Organization
#
# The main function of this configuration file is to allow user to specify
# the root Configuration directory to activate. The active Configuration
# directory is represented by _USTN_CONFIGURATION. By default, it points to
# the installed Configuration defined by _USTN_INSTALLED_CONFIGURATION,
# which can consist of example WorkSpaces and WorkSets.
# If your organization has its own Configuration directory, you can define
# _USTN_CUSTOM_CONFIGURATION to that directory path and use it as follows.
#
#_USTN_CUSTOM_CONFIGURATION = D:/.../MyConfiguration/
#_USTN_CONFIGURATION : ${_USTN_CUSTOM_CONFIGURATION}
#----------------------------------------------------------------------

#----------------------------------------------------------------------
# START: The section defines user selection at the time of installation.
# These lines are generated by installer.

%if !defined (_USTN_USER_CONFIGURATION)
%if defined (_USTN_CUSTOM_CONFIGURATION) && ($(_USTN_CUSTOM_CONFIGURATION) != "") && exists ($(_USTN_CUSTOM_CONFIGURATION))
_USTN_CONFIGURATION = $(_USTN_CUSTOM_CONFIGURATION)
%endif
%endif

Si un emplacement de configuration personnalisée n'est pas défini lors de l'installation, alors _USTN_CONFIGURATION indique le dossier de configuration livrée défini par _USTN_INSTALLED_CONFIGURATION. Si un emplacement de configuration personnalisée est défini lors de l'installation, son chemin est défini dans _USTN_CUSTOM_CONFIGURATION.
