Fix Microsoft Word Crashing on Mac Missing Forms Framework
Question details
The user needs to resolve a recurring crash in Microsoft Word for Mac caused by a missing or invalid Forms.framework library.

- Product
- Microsoft Word for Mac
- Device & OS
- macOS
- Scenario
- Trying to launch or use Microsoft Word on a Mac computer, but the application quits unexpectedly.
- Observed behavior
- Microsoft Word crashes upon launch or during operation, generating an error report that indicates the Forms.framework dynamic library cannot be loaded due to a damaged installation or an invalid code signature.
Ensure all your unsaved work in other Microsoft Office applications is securely saved and completely close all running Office programs before beginning the troubleshooting steps.
Uninstall and Reinstall Microsoft Word
A clean reinstallation is the most effective way to restore missing or corrupted core framework files for Microsoft Word.
Since the crash report indicates that Word cannot load a required dynamic library, the installation is likely damaged. Reinstalling macOS is generally unnecessary; reinstalling the Word app itself will replace the missing Forms.framework.
Ensure Microsoft Word and all other Office applications are completely closed on your Mac.
Open Finder, navigate to your Applications folder, locate Microsoft Word, and drag the icon into the Trash.
Click the Apple menu and select Restart. Once the Mac boots up, right-click the Trash icon in your Dock and select Empty Trash.
Go to the official Microsoft website, sign in to your Microsoft account, download the latest official macOS installer for Word, and run it to reinstall the application.

Remove Microsoft Word Preference Files
Corrupted preference files can cause unexpected crashes upon launch. Clearing them forces Word to generate fresh configuration settings.
Disable Incompatible Add-ins
Third-party extensions like Grammarly or EndNote might conflict with Word's framework libraries, causing the application to crash.
Switch to WPS Office for a Stable Mac Experience
If Microsoft Word continues to crash or you are tired of dealing with missing framework errors, consider switching to WPS Office. It provides a lightweight, highly compatible, and free alternative for Mac users to open, edit, and create documents seamlessly.
- 1. Download WPS Office: Visit the official WPS website and download the macOS version of WPS Office.
- 2. Install on Your Mac: Open the downloaded installer and drag the WPS Office icon into your Applications folder.
- 3. Open Your Word Files: Launch WPS Writer and directly open your existing .docx files to continue working without missing framework errors.

Frequently Asked Questions
Why does the missing Forms.framework error occur in Word for Mac?
This error typically happens when Microsoft Word's installation files become corrupted, a macOS system update causes compatibility issues with existing app libraries, or a third-party add-in interferes with the application's core components.
Will running Disk Utility fix the Word crashing issue?
Running Disk Utility's First Aid can fix basic macOS file system errors, but it usually does not repair application-specific missing frameworks. A full reinstallation of Microsoft Word is much more effective for this specific crash.
Are my Word documents lost if the application keeps crashing?
No, your documents are securely saved on your Mac's hard drive or your cloud storage. The application crash only affects the software itself, not your created .docx files. You can still open them once Word is fixed or by using an alternative program like WPS Office.
