March 7, 2017, update for Project 2016 (KB3178669)

Applies to: Project Standard 2016Project Professional 2016

This article describes update KB3178669 for Microsoft Project 2016, which was released on March 7, 2017. 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?)
This update fixes the following issues:
  • The Visual Basic Applications ScreenUpdating property does not work as expected in Project 2016. Instead of freezing the screen content when the code runs, the screen continues to update. This produces screen flicker and causes the code to run slower.
  • Assume that a project manager opens a project in Project 2016 that has been successfully used with Project 2013. In this situation, when actual work values are observed in the Task Usage view, it is found that, for some resources, the actual work has been moved from the dates on which it was entered.
  • In the Progress Lines dialog box, you select to display progress lines in relation to the baseline plan instead of the default actual plan. In this situation, the progress line does not draw as expected.
  • When you open an .xml file within the Import Wizard and select the As a new project option, Project 2016 may crash.
  • Assume that you open a project plan, and transfer local resource custom field lookup table values to an enterprise resource enterprise field. Then you save the project plan to a Project server. In this situation, some custom enterprise resource lookup table values may be lost.
  • In some cases, enterprise custom field data may be lost from a project after a status update has been applied, and the project is then opened in Project Professional 2016.
