You must be logged on as an administrator or a member of the Administrators group in order to complete this procedure. If your computer is connected to a network, network policy settings may also prevent you from completing this procedure.
Open Regional and Language Options in Control Panel.
On the Languages tab, under Supplemental language support, select the Install files for complex script and right-to-left languages check box.
Click OK or Apply.
After the files are installed, you must restart your computer.
To open Regional and Language Options, click Start, click Control Panel, click Date, Time, Language, and Regional Options, and then click Regional and Language Options.
The complex script and right-to-left languages include Arabic, Armenian, Georgian, Hebrew, the Indic languages, Thai, and Vietnamese. The files for most other languages are installed on your computer automatically by Windows.
It is recommended that you install these files only if you are going to be entering or receiving text in one or more of these languages. Installing the language files may slow down your computer's performance slightly.
Once you install the language files, you must add the individual languages for which you want to enter and display text. Once you add a language, the language is loaded into memory every time you start your computer. For more information, click Related Topics.
