Locate and Remove Duplicate Copies of Microsoft Word

Having multiple versions of Microsoft Word installed can cause conflicts that prevent the application from launching correctly. Removing outdated copies usually resolves this issue.

macOS can become confused if an older copy of Word attempts to launch instead of the current Microsoft 365 version. Clearing out redundancies ensures the correct app runs.

Search for Microsoft Word

Open Spotlight by pressing Command + Space, or open a new Finder window and use the search bar to look for 'Microsoft Word'.

Identify duplicate applications

Review the search results under the Applications category to see if there are multiple copies of Microsoft Word.

Move outdated copies to Trash

Drag the older or duplicate copies of the Microsoft Word application to the Trash on your dock.

Empty the Trash

Right-click the Trash icon and select 'Empty Trash' to permanently delete the conflicting files.

Restart and test

Restart your MacBook Air and try launching Microsoft Word from the Applications folder.

Locate and Remove Duplicate Copies of Microsoft Word

Reset File Associations: If clicking a document still opens the wrong app, right-click the file, select 'Get Info', change 'Open with' to the current Microsoft Word, and click 'Change All'.

Solution 2

Completely Uninstall and Reinstall Microsoft 365

If removing duplicates fails to fix the issue, the core application files might be damaged. Reinstalling Microsoft 365 ensures you have clean, functional software.

Frequently Asked Questions

Why is Microsoft Word not opening while Excel works fine on my Mac?

This typically occurs due to corrupted Word-specific preference files, a damaged Word application package, or conflicting duplicate versions of Word installed on your Mac, while Excel's independent files remain intact.

Will uninstalling Microsoft Word delete my saved documents?

No, uninstalling the Microsoft Word application only removes the software files. Your personal .docx documents are stored separately on your hard drive or in cloud storage and will not be affected.

How do I force quit Microsoft Word if it's stuck on the loading screen?

Press the Command + Option + Esc keys simultaneously to open the Force Quit Applications window. Select Microsoft Word from the list and click the 'Force Quit' button.

What should I do if my Mac says 'Application not opened' for Word?

This error often points to duplicate app conflicts or macOS permission issues. Empty your Trash if it contains old Word copies, restart your Mac, and if the issue persists, perform a clean reinstall of Microsoft 365.
