September 6, 2016, update for Project 2013 (KB3115493)

Applies to: Project 2013 StandardProject Professional 2013

This article describes update KB3115493 for Microsoft Project 2013, which was released on September 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

  • Enables DialogAPI 1.1 requirement set in Office 2013 applications and Mailbox 1.4 requirement set in Outlook 2013.
  • Fixes the following issues:
    • When you merge or append a tab-delimited text document into an existing project, the changes that are made can't be saved in Project 2013.
    • Assume that you create a project from a template in Project Web App. When you try to enter the timephased cost or actual cost for a cost resource in Project 2013, the values that you enter can't be applied, and Project 2013 may crash.
    • When status updates are applied, trailing timphased actual work values are created. This causes finish dates are later than expected.
