Some TestComplete subsystems support only one Unicode language at a time. You can set the system language both from TestComplete scripts and manually. This topic describes the second option. To learn how to set the system language from scripts, see Setting the System Language From Scripts.
The Unicode language to be supported by the TestComplete user interface and other non-Unicode programs running on your computer is specified by the Language for non-Unicode programs system option. You can set this option in the Windows Control Panel.
Alternatively, you can set the system language from scripts.
