Configuring the Creo Application Startup
When you configure the startup of a Creo application, an executable file named <app>.exe, for example, schematics.exe and one or more configuration files (.psf) are created for each startup configuration. The configuration file contains an area where you can specify and set user-defined environment variables. This user-defined information is preserved during reconfiguration and update installations of the Creo applications. A configuration file is created when you complete the installation of a Creo application.
The configuration file is created in the <creo_loadpoint>\<datacode>\<app_name>\bin directory.
You can run <creo_loadpoint>\<datacode>\<app_name>\bin\<app_name>.exe to display a list of the available startup configurations.
The startup command is a combination of the startup executable and the configuration file. For example,
schematics.exe <filename>.psf
In this case, <filename> is the name of the configuration file.
A sample configuration file follows. The text is the default information that is used when you start Creo Schematics. The bold text following the // USER - PSF section is the user-defined information for starting Creo Schematics.
* 
Modify only the last text line of this sample configuration file.
// PTC - PSF file: schematics
//
PRODUCT=Creo Schematics
DESC=Creo Schematics (default)
//
ENV=BROWSER=iexplore
ENV=PDM_LDB_PATH:=!PDM_LDB_PATH:%HOMEDRIVE%%HOMEPATH%
ENV=PATH+=%PRO_DIRECTORY%\%PRO_MACHINE_TYPE%\deflib
ENV=PATH-=%PRO_DIRECTORY%\%PRO_MACHINE_TYPE%\lib

ENV=CREOSCHEM_FEATURE_NAME=CREOSCHEM_INHOUSE CREOSCHEM_BASIC ()
RUN="%PRO_DIRECTORY%\%PRO_MACHINE_TYPE%\creoschematics\bin\uiengine.exe"
// USER - PSF
// Add User specific environment or run applications below here
ENV=PRO_LANG=german
You can set the value of an environment variable or specify the startup of a third-party application under the // USER - PSF section of the configuration file.
If you run the Creo application without creating a configuration file, an error message indicates that the Creo application cannot be started. In such cases you must run ptcsetup from the <creo_loadpoint>\<datacode>\<app_name>\bin\<app_name> folder and create a PTC Startup File (PSF) for that Creo application. You can then run that Creo application using the corresponding PSF file.
If you create only one configuration file, the Creo application uses this configuration file by default.
