To get the latest update, open an Office for Mac application, go to the Help > Check for Updates menu, and follow the instructions in the AutoUpdate app.

Since this is a third party app what does Microsoft Support suggest? This maybe your best bet to resolve your issue.

You are running High Sierra, but what version of MS Word?

Before High Sierra launched, Microsoft announced that it would not be offering “formal support” for its Office 2011 apps in macOS 10.13 High Sierra. Support for Office 2011 for Mac was due to end on 10 October 2017 anyway.

This doesn't mean that your Office 2011 apps will not work in High Sierra, but it is possible that you will encounter issues with them - and Microsoft will not be addressing any issues with the suite of apps including:

• Word 2011
• Excel 2011
• PowerPoint 2011
• Outlook 2011

We have tested Word 2011 and it does seem to work in High Sierra, but we would advise against relying on it, just in case a glitch causes you to lose your work.

The current version is 16.13. Update to the current version using the MS Updater before trying anything else.
