Remove the linkCreation.dotm Add-in via Word Menu
This is the most straightforward method to resolve the error by disabling the problematic Adobe Acrobat add-in directly within Microsoft Word.
Launch Microsoft Word on your Mac to access the main interface.
On the top Mac menu bar, click on 'Tools' and select 'Templates and Add-ins' from the dropdown menu at the bottom.
Under the 'Global Templates and Add-ins' section, locate and select the item named 'linkCreation.dotm'. Click the minus (-) button to delete it.
Close Microsoft Word completely and open it again to verify that the runtime error has been resolved.

Delete Startup Add-in Files Using Mac Terminal
Use this method if you manage multiple Macs or if the error persists across Word, Excel, and PowerPoint despite trying the menu option.
Avoid Add-in Conflicts with WPS Office for Mac
If third-party add-ins like Adobe Acrobat constantly crash your Microsoft Office apps, consider switching to WPS Office. It provides a lightweight, highly compatible, and stable environment for all your document needs without the hassle of intrusive plugins.

Frequently Asked Questions
Why does Runtime Error 53 keep coming back after I fix it?
The error often returns because Adobe Acrobat Pro updates automatically reinstall the 'linkCreation.dotm' file into the Microsoft Office startup folders. You will need to remove the add-in again after an Adobe update.
What is the MacPDFM.framework component?
MacPDFM.framework is a component of Adobe Acrobat Pro designed to integrate PDF creation features into Microsoft Office on macOS. When it fails to load properly due to compatibility issues, it triggers Runtime Error 53.
Does this runtime error affect Microsoft Excel and PowerPoint as well?
Yes, the Adobe Acrobat installer places similar startup files into the Excel and PowerPoint startup directories, which can cause related startup errors across the entire Microsoft Office suite on your Mac.
Is there a permanent fix for this Adobe Acrobat error?
Currently, removing the add-in files manually is a workaround rather than a permanent fix. A definitive resolution requires an official software patch from Adobe to address the root compatibility issue with Microsoft Office for Mac.
