How to Fix Microsoft Office License Removal Tool Errors on macOS
Product
Microsoft Office 2021
Device & OS
macOS Ventura
Scenario
Attempting to completely remove existing Office licenses to resolve ongoing installation failures.
Observed behavior
The License Removal Tool and Office installer repeatedly fail to execute. Standard fixes like manually deleting Library files or basic reinstallations do not resolve the issue, suggesting potential disk permission errors or a damaged user profile.
Before you start

Ensure you back up your Mac using Time Machine before performing disk repairs or creating new system profiles to prevent any accidental data loss during the troubleshooting process.

Solution 1Recommended

Run Disk Utility and Test in a New User Account

Use macOS built-in tools to repair disk errors and isolate the issue to a corrupted user profile.

If the License Removal Tool fails, the problem is often tied to your specific macOS user profile or disk permissions rather than the application itself. Testing the tool in a fresh macOS account helps isolate and bypass the cause.

1
Open Disk Utility

Go to Applications > Utilities > Disk Utility, select your startup disk from the left panel, and click 'First Aid' to check and repair any underlying disk errors.

2
Create a New User Account

Navigate to System Settings > Users & Groups on macOS Ventura, and click 'Add Account' to create a new Administrator profile.

3
Log into the New Account

Log out of your current session and log back in with the newly created Administrator account credentials.

4
Run the Removal Tool

Download a fresh copy of the Office License Removal Tool and the Office 2021 installer from the official Microsoft website, then attempt to run them in this new environment.

Run Disk Utility and Test in a New User Account
Profile Corruption Identified: If the tools work perfectly in the new account, your original user profile is likely damaged. You can simply migrate your personal files to the new account instead of erasing your entire Mac hard drive.

Frequently Asked Questions

Why does the Office License Removal Tool fail on macOS Ventura?

Failures are typically caused by corrupted disk permissions, damaged macOS user profiles, or restricted system access to specific Library folders necessary for license removal.

Should I manually delete Office Library files instead of using the removal tool?

It is not recommended. Manually deleting random Library files may not fully remove the license, leaving leftover registry items that can cause further software conflicts. Always try repairing your disk or using a new user account first.

Do I need to erase my entire Mac hard drive to fix Office installation errors?

No. Erasing your entire drive should only be considered an absolute last resort if all other recovery options, including creating a new user profile and running Disk Utility First Aid, have completely failed.
