Fixes or workarounds for recent issues in PowerPoint for Mac

Last updated: November 2016

PowerPoint for Mac crashes and slow performance

ISSUE

Apple released macOS 10.12 Sierra on 9/20/2016. Some customers are reporting Office 2016 for Mac applications are closing unexpectedly, or crashing when an Office application is launched, or when the computer is moved between Wi-Fi networks (e.g. moving a laptop from home to work).

Microsoft is working with Apple to resolve this issue. We recommend customers in a workplace or school network configuration do not upgrade to macOS Sierra at this time.

WORKAROUND

Turning off “Auto Proxy Discovery” or “Automatic Proxy Configuration” is a possible workaround, if allowed by your organization’s network configuration.

  1. Go to System Preferences and open Network.

  2. Click on Advanced and go to Proxies.

  3. Check if "Auto Proxy Discovery" or "Automatic Proxy Configuration" is turned on.

Contact your local network administrator for more information on your network settings.

We will update this content when more information is known, including a fix or additional workaround.

ISSUE

If you have Silverlight installed and tried installing the latest version of Office 2016 for Mac via Microsoft AutoUpdate, the AutoUpdate tool crashes.

You may be experiencing this issue due to an older version of Silverlight installed in your machine. We recently have released a fix to protect Microsoft AutoUpdate from crashing due to an older version of Silverlight.

STATUS: FIXED

To fix this issue, please do the following:

Update to the latest version of Silverlight (version 5.1.50901.0)

  1. Follow the steps to install the latest version of Silverlight: https://www.microsoft.com/getsilverlight

  2. Open Safari, and on the top menu, click Safari > Preferences.

  3. Go to Security and then in the section “Internet plug-ins” click Website Settings….

  4. On the left side list of plug-ins, select Silverlight and then make sure that “Allow” is selected from the drop down menu.

  5. Once the Silverlight update is complete, try updating Office for Mac via Microsoft AutoUpdate.

Install the latest version of Office 2016 for Mac, version 15.28.0 (build 16111300)

  • Use Help > Check for Updates from any of the Office 2016 apps to get updates to the newer build.

  • If for some reason you can’t update via Help, you can manually download and install the new build from this article.

You encounter broken images and an rld2/rld3 error. For example, you see the message "The image part with relationship ID rId2 was not found in the file."

This issue has been fixed in build 15.28.16111501, released on 11/15, and later. Please update to the latest build by going to Help > Check for Updates from any of the Office 2016 apps.
