在安装期间定义“自定义配置”路径时，会将其写入 ConfigurationSetup.cfg 文件中。这样会在 _USTN_CUSTOM_CONFIGURATION 配置变量中定义根配置目录。msconfig.cfg 包含 ConfigurationSetup.cfg，具体如下：

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

以下为所提供的 ConfigurationSetup.cfg 的内容：

#---------------------------------------------------------------------- #  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.缺省情况下，将指向 _USTN_INSTALLED_CONFIGURATION 定义的已安装配置 #，# 可包含工作空间和工作集示例。# 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.[General] _USTN_CUSTOM_CONFIGURATION=

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