This article describes update 4018369 for Microsoft Office 2016 that was released on May 1, 2018. This update has a prerequisite.

Be aware that the update on the Microsoft Download Center applies to the Microsoft Installer (.msi)-based edition of Office 2016. It doesn't apply to the Office 2016 Click-to-Run editions, such as Microsoft Office 365 Home. (How to determine?)

Improvements and fixes

This update fixes the following issue:

In some cases, some versions of Office don't support the requirements that a Web add-in specifies for the Office 365 experience. Therefore, the Web add-in that's designed to work with both Office 365 and earlier versions of Office may not be displayed in earlier versions of Office.
