About Auxiliary Applications
In Creo Direct, the Auxiliary Applications command on the Tools tab is used to manage Creo Object TOOLKIT C++ and Creo Object TOOLKIT Java customizations. It is an entry point for these external applications you create for use in Creo Direct.
 
* Creo Direct does not allow you to customize Creo Parametric TOOLKIT and J-Link applications.
The Auxiliary Applications command opens the Auxiliary Applications dialog box. It allows you to:
Search for registry files (.dat files) in order to register external applications.
List all available external applications.
Start, stop, or delete registered applications.
For more information about Creo Parametric TOOLKIT, Creo Object TOOLKIT C++, Creo Object TOOLKIT Java, or J-Link, refer the respective online documentation.
