December 6, 2016, update for Project 2013 (KB3127978)

Applies to: Project Standard 2013Project Professional 2013

This article describes update KB3127978 for Microsoft Project 2013, which was released on December 6, 2016. This update has a prerequisite.

Be aware that the update in the Microsoft Download Center applies to the Microsoft Installer (.msi)-based edition of Office 2013. It doesn't apply to the Office 2013 Click-to-Run editions, such as Microsoft Office 365 Home. (How to determine?)

Improvements and fixes

  • Update the translation of the confirm message on a dialog box that appears when you change and close a project in Project 2013.

  • Fixes the following issues:
    • Ribbon buttons such as the Edit Item button may be disabled on a SharePoint tasks list if there are multiple pages of tasks.

    • After you save a baseline, timephased work and cost values aren't displayed as expected. For example, you may see work and cost during periods where no work or cost exists.

    • When you save a Project 2003 project to Project Server, resource custom field values may be lost.

    • When you open an XML file, you may find that work on existing assignments is lost, assignment delay is reset to zero, and assignment finish dates are incorrect.

    • You may find that the modified date for a project as seen within the Clean Up Cache dialog box incorrectly shows the date and time as Coordinated Universal Time (UTC) instead of being adjusted to your time zone.

    • In a master project, when you view the finish date of an inserted project summary task (this is the task that represents a subproject), you may find that it doesn't reflect the latest finish date of the tasks in the subproject.
