April 3, 2018, update for Project 2016 (KB4018320)

This article describes update 4018320 for Microsoft Project 2016 that was released on April 3, 2018. 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 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:

• When a task custom field formula is applied, and it also uses the formula for summary and grouping rows, the summary row displays "#ERROR". In addition, the grouping row displays incorrect values.
• The Change Working Time dialog box enables you to select a date and to see the working shifts for that day listed in the Working times section. For example, a date shows working shifts of 8:00 AM to 12:00 PM and 1:00 PM to 5:00 PM. In some cases, you may be unable to see all the defined shifts for the given date because it's hidden behind the text that tells you the date's base calendar.
• You open a project from the Project Center while using the Google Chrome browser. Then you see the following error message:

  Sorry, we were unable to open your project. Please try again. If this happens again, contact your administrator.

• Consider the following scenario:

  • You have a project plan that has many tasks with long durations.
  • You may have some baselines established.
  • You save the project plan to an XML file.
  • You open the XML file.

  In this case, if you use the 32-bit version of Project, it may crash. If you use the 64-bit version of Project, you notice that it takes a long time to open the file and Project uses many gigabytes of memory. When you look at the size of the XML file, you'll also notice that it is hundreds of megabytes in size. 

  Note To fix this issue, you also have to set the value of the registry key XmlDisableTimephasedSplitByDay to 1. See Registry information for more information.

This update also contains the following improvement:

• When you save a project to the XML format, the following pieces of new information are exported:
  • The build number of Project that created the XML file.
  • Project, task, resource and assignment GUIDs.
  • Names of views.
  • Names of tables.
  • Names of filters.
  • Names of groups.
  • Names of data import and export maps.
  • Names of reports.
  • Names of drawings.

  Project exports these pieces of information but does not read them when you open or merge an XML file. Therefore, you can't, for example, add or change view names within an XML file, and have Project read and understood the information.

  Note If you do not want your XML files to have this new information, you can set the following registry key:

  • Location: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\MS Project\Options\Save\
  • Type: DWORD
  • Name: SimpleXmlexport
  • Value: 1
