Before switching languages, be sure the desired language has been installed (see Installing Intellect or Installing the language).
To switch the Intellect Software System's interface language, do the following:
- Shut down the Intellect Software System.
- Launch the system's advanced settings utility tweaki.exe. The utility is accessed through Start –> Intellect –> Utilities, or by going to <Intellect installation directory>\ Tools\.

- From the Application language dropdown list, select the desired interface language for the Intellect Software System (1).
- Click OK (2).
- Launch the Intellect Software System.
This completes the process of switching languages.
