Question details

The user needs to transfer a retail license of Microsoft Office Home and Business 2024 from a Mac to a new Windows PC, but removing the application from the Mac did not release the license.

Product
Microsoft Office Home and Business 2024
Device & OS
Mac and Windows PC
Scenario
Migrating an existing software license to a new computer running a different operating system.
Observed behavior
Uninstalling or removing the Office application from the Mac does not automatically deactivate the installation, preventing activation on the new Windows PC.
Before you start

Verify that your Office Home and Business 2024 license is a cross-platform retail version (not restricted exclusively to Mac), and ensure you have the login credentials for the Microsoft account used to purchase the software.

Solution 1Recommended

Deactivate and Reinstall via Microsoft Account

Manage your device installations directly from your Microsoft account portal to release the license for your new Windows PC.

Because Office licenses are tied to your Microsoft account rather than the physical installation files, simply deleting the app from your Mac is not enough. You must digitally deactivate the previous installation.

1
Sign in to Microsoft Services

Navigate to https://account.microsoft.com/services in your web browser and log in with the Microsoft account associated with your Office Home and Business 2024 purchase.

2
Locate Your Subscription

Scroll to the 'Services & subscriptions' section to find your Office Home and Business 2024 license.

3
Deactivate the Mac Installation

Look for the previous Mac device under your installations. If the option is available, select 'Sign out of Office' or 'Deactivate' to remove the license from the Mac.

4
Install on Windows PC

While logged into the same portal on your new Windows PC, click the 'Install' button next to your Office product to download and activate the software.

Platform Restrictions: If you do not see an option to install on Windows, your original purchase may have been a Mac-specific license. Only cross-platform retail licenses can be transferred between operating systems.

Frequently Asked Questions

Does uninstalling Office from my Mac automatically release the license?

No. Dragging the Microsoft Office application to the Trash or running an uninstaller tool on a Mac removes the local files but does not communicate with Microsoft's activation servers. You must manually deactivate the installation through your Microsoft account online.

Can I transfer a Mac-only version of Office 2024 to Windows?

If your Office Home and Business 2024 license was explicitly purchased as a Mac-only version, it cannot be transferred to a Windows PC. Cross-platform transfers are only permitted for unrestricted, standard retail licenses.

What should I do if the activation wizard says my product key is already in use?

This error occurs when the license is still tied to your previous Mac in Microsoft's system. You will need to contact Microsoft Support directly, provide your account details or proof of purchase, and request that they manually release the license so you can activate it on your new Windows PC.
