Scenario
Launching Microsoft Word or opening a Word document on a Mac device that has Adobe Acrobat installed.

Solution 1Recommended

Remove the Adobe Acrobat Add-in from the Word Startup Folder

This is the most common and effective fix for Runtime Error 53, which is often caused by an outdated Adobe Acrobat add-in file called linkCreation.dotm.

When Adobe Acrobat is installed on your Mac, it sometimes adds a template file to Word's startup folder to enable PDF creation features. If this file becomes incompatible with your current version of macOS or Word, it triggers Runtime Error 53.

1
Close Microsoft Word

Right-click the Microsoft Word icon in your Mac's Dock and select 'Quit' to ensure the application is completely closed.

2
Open the hidden Library folder

Open Finder. Click on 'Go' in the top Apple menu bar, press and hold the 'Option' key on your keyboard, and click on 'Library' when it appears in the dropdown list.

3
Navigate to the Word Startup directory

Follow this exact path: Group Containers > UBF8T346G9.Office > User Content > Startup > Word.

4
Delete the linkCreation.dotm file

Look for a file named 'linkCreation.dotm' (or any other suspicious Adobe Acrobat add-ins). Drag this file to the Trash.

5
Restart Microsoft Word

Open Microsoft Word again. The startup process should now complete smoothly without displaying Runtime Error 53.

Remove the Adobe Acrobat Add-in from the Word Startup Folder
Accessing the Library Folder: The Library folder is hidden by default on macOS. You must hold down the 'Option' key while the Finder 'Go' menu is open to reveal it.

Frequently Asked Questions

What is Runtime Error 53 in Word for Mac?

Runtime Error 53 usually occurs when an incompatible, outdated, or corrupted add-in attempts to load a dynamically linked library file that cannot be found during Word's startup process.

Why does the linkCreation.dotm file cause this error?

The linkCreation.dotm file is a template add-in installed by Adobe Acrobat to facilitate PDF creation directly from Word. When macOS or Word updates are applied, this add-in can lose compatibility and trigger an error if it isn't also updated.

What should I do if linkCreation.dotm is missing from the Startup folder?

If the specific file is not present, look for other unfamiliar add-ins in the same 'Startup > Word' folder and temporarily remove them. If the error persists, the issue might lie within a corrupted Adobe Acrobat installation, requiring a clean reinstallation or contacting Adobe Support.
