International support for Directory Toolkit is enabled via a "language dll", named 'dtlang.dll', that is installed based on user choice at the time of program installation.
In the past the language interface was added (or removed) in separate step. It is no longer necessary to download and install a separate language interface. The installers for the demo and registered versions of the program now include all available languages and documentation.
To change or remove the language choice simply re-run the program installer.
See the Language Overview for more information
