This article describes update 4475580 for Microsoft Office 2016 that was released on August 6, 2019.

Be aware that the update in 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 (see What version of Office am I using?).

Improvements and fixes

This update fixes an issue in which Setting API doesn't work in the Office JavaScript library in the following scenario:

  • If an Office JavaScript Dialog API is called in an Office Add-in, the Office JavaScript Setting API in the Office Add-in will stop working after the call. Therefore, the caller will get "Access Denied" error on the Setting API writing operation.
