The Creo TOOLKIT registry file has the same format as the Pro/DEVELOP registry file. The search path used by Creo TOOLKIT to find the registry file is like that used by Pro/DEVELOP. However, the file name prodev.dat is now replaced by creotk.dat or protk.dat, and the configuration file option prodevdat is now either creotkdat, or protkdat, or toolkit_registry_file. To convert from Pro/DEVELOP to Creo TOOLKIT, simply substitute these names.

For an extended period, the search path for the Pro/DEVELOP registry file will continue to be used by Creo+, in addition to the search path for Creo TOOLKIT. Therefore, you do not need to rename the Pro/DEVELOP registry file or configuration file option immediately.
