Even if you install the MultiLanguage Pack to enable multilingual features in Microsoft Office, you still need to verify that your system supports the language you want to use.

To do so, follow these steps:
Office installs your selected languages; new features can be added to PowerPoint and other Office applications based on your language choice.
