Fixes or workarounds for recent issues in Word for Mac

Last updated: December 2016

Word for Mac crashes and slow performance


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.


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.

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.


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:

  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.

Issues affecting Word for Mac features and add-ins

When using Acrobat PDFMaker add-in Word 2016 for Mac 64-bit (version 15.25 or later), you may experience one of the following:

  • Compile error in hidden module: link” error message when opening Word 2016 for Mac.

  • Create PDF icon is disabled or grayed out on the Acrobat tab
    "Create PDF" button is disabled in Acrobat PDFMaker add-in

Adobe released the latest version of the Acrobat PDFMaker. To download the latest version, visit PDFMaker support for 64-bit Office 2016 on Mac OS for updates to the add-in.

When using JustSystems ATOK add-in in Office 2016 for Mac 64-bit (version 15.25 or later), you may experience one of the following:

  • Word or Excel error message: "Compile error in hidden module: 'Module1'. This error commonly occurs when code is incompatible with the version, platform, or architecture of this application."

  • Excel error message:
    "Compile error in hidden module: 'ThisWorkbook'. This error commonly occurs when code is incompatible with the version, platform, or architecture of this application."

This is a known compatibility issue. For more information on this error, go to (Note: Link goes to JustSystems Japanese language website).

When typing a document in a bi-directional language (right-to-left) such as Hindi, Hebrew, or Persian, and then formatting the text using a numbered list, the numbers change back to English (Arabic: 1, 2, 3) from the bi-directional language.

We are currently working on a fix for this issue. In the meantime, you can do the following workarounds.

  • If you’re not working with mixed content (in other words, Hindi only), then choose File > Options > Advanced. Then under Show document content, next to Numeral, click Hindi.

  • If you are working with mixed content (both Hindi and Arabic), create a two column table. In one column, put the left-to-right Arabic numbers, and in the other column, put the right-to-left Hindi text. This solution will avoid the numbered list until the coming fix is released.
