Device & OS: macOS
Scenario: Launching Microsoft Word from Finder, Launchpad, or the Dock.

Find and Remove Duplicate Word Installations

macOS might be trying to open an outdated or conflicting copy of Microsoft Word by default. Removing old versions typically resolves this error.

Sometimes during updates or migrations, older versions of Microsoft Word are left behind on your Mac. When you attempt to open a document, macOS may default to the unsupported older application, causing a launch failure even if your current Microsoft 365 subscription is valid.

Search for multiple copies

Press Command + Space to open Spotlight Search, or open Finder and use the search bar to look for 'Microsoft Word'.

Identify and delete old versions

Look for duplicate Word applications in the search results. Drag any outdated or duplicate copies of Microsoft Word to the Trash.

Empty the Trash and restart

Right-click the Trash icon in your Dock and select 'Empty Trash'. Once emptied, click the Apple menu and select 'Restart' to reboot your Mac.

Reset file associations

Right-click any .docx file, select 'Get Info', locate the 'Open with' section, choose the current version of Microsoft Word, and click 'Change All'.

Quick Fix: Ensuring only a single, up-to-date version of Word is installed prevents macOS from triggering application-opening errors caused by conflicts.

Solution 2

Perform a Clean Reinstallation of Microsoft 365

If removing duplicates does not work, completely uninstalling and reinstalling the Office suite will replace corrupted application files.

Frequently Asked Questions

Why is Word not opening but Excel is working fine on my Mac?

This usually happens due to duplicate or outdated Word application files conflicting with macOS, or corrupted Word preference files. Since Word and Excel operate as separate applications within the suite, corrupted files in one will not necessarily affect the other.

Will uninstalling Microsoft Word delete my saved documents?

No, uninstalling the Microsoft Word application only removes the program files. Your saved .doc and .docx files, as well as documents stored on OneDrive, will remain safe and unaffected.

How do I make sure macOS always opens files with the newest version of Word?

Right-click any Word document (.docx) in Finder, select 'Get Info', and look for the 'Open with' dropdown. Select the newest version of Microsoft Word, then click the 'Change All' button underneath it to apply this setting system-wide.
