Remove Old Licenses and Reinstall Office 2024

Use this method to completely clear residual Office 2019 or Microsoft 365 licenses that are preventing Office 2024 from activating.

When upgrading to a new version of Office on a Mac, old license files often remain in the system library. The official Microsoft License Removal Tool is required to delete these hidden files so the new product key can be properly recognized.

1
Uninstall existing Office apps

Open the Applications folder on your Mac and drag the Microsoft Word, Excel, and PowerPoint apps to the Trash to remove the old Office installation.

2
Run the License Removal Tool

Download the official Microsoft Office License Removal Tool for Mac. Run the package installer and follow the on-screen prompts to clear all old Office 2019 or Microsoft 365 activation data from your system.

3
Download the Office 2024 installer

Open your web browser and navigate to account.microsoft.com/services. Sign in using the exact Microsoft account associated with your Office 2024 purchase, then locate your product and click Download.

4
Install and activate

Run the newly downloaded Office 2024 installer. Once the installation is complete, launch Microsoft Word, select 'Sign In' from the activation prompt, and enter your Microsoft account credentials to apply the new license.

Activation Errors: If you receive an error message upon entering the product key a second time, try checking the app's 'About' section; sometimes the activation successfully registers despite the error dialogue.

Frequently Asked Questions

Why is my Mac still showing Office 2019 after I installed Office 2024?

Macs often retain previous Office license files in the hidden system library even after the main applications are uninstalled. You must use the Microsoft License Removal Tool to delete these background files before the Office 2024 license can take effect.

Can I have both Office 2019 and Office 2024 installed on my Mac?

It is highly recommended to completely uninstall the older version before installing Office 2024. Keeping both versions installed simultaneously can lead to persistent license conflicts and activation errors.

What should I do if the license removal tool doesn't fix the activation?

If you have uninstalled the old apps, run the license removal tool, and reinstalled from your Microsoft account but still face issues, you should contact Microsoft Support directly. Be ready to provide your purchase details and current macOS version (e.g., Sonoma 14.6.1).
