Download Office 2016 proofing tools for different languages from Office.com

Have you already upgraded to Office 2016? If so, you might be in the need to the language packs (proofing tools) for your new product version. As you might guess, the proofing tools you used with previous Office versions (say, 2013) won't work with Office 2016.

To download the proofing tools, visit this page on Office support.

From this page, you can download language packs for all supported languages. You will get a separate installation program for each particular language. Install it as you normally would, and then Word, Outlook, PowerPoint and so on will get support for the new language you installed.

Hope this helps!
