Fix Microsoft 365 Family Activation Issues on a Second Windows Laptop
Question details
The user is unable to activate a Microsoft 365 Family subscription on a second laptop, as the system incorrectly identifies the installation as Microsoft Office 2016 Professional Plus instead.

- Product
- Microsoft 365 Family
- Device & OS
- Windows 11
- Scenario
- Installing and activating an existing Microsoft 365 Family subscription on a secondary Windows laptop.
- Observed behavior
- The Office suite remains unactivated and displays as Office 2016 Professional Plus. Standard reinstallation and PC resets fail to resolve the license conflict.
Ensure you are connected to the internet and have the correct login credentials for the Microsoft account linked to your Microsoft 365 Family subscription.
Completely Remove Conflicting Licenses and Reinstall Microsoft 365
Use the official Microsoft Support and Recovery Assistant (SaRA) uninstall tool to wipe out hidden Office 2016 registry keys that are blocking your new activation.
Standard uninstalls or PC resets often leave behind legacy license files or registry entries. If your laptop previously had Office 2016 installed or came with a pre-installed trial, these remnants force the new installation to recognize the old license instead of your active Microsoft 365 Family subscription.
Navigate to https://aka.ms/SaRA-officeUninstallFromPC to download the Microsoft Office uninstall support tool.
Launch the downloaded file, select your current Office installations from the list, and follow the prompts to completely remove all Microsoft Office data from your PC. Restart your laptop once finished.
Go to https://www.office.com in your web browser and sign in using the Microsoft account that holds the Microsoft 365 Family subscription.
Click the 'Install Office' button on your account dashboard and follow the on-screen instructions to download and install a fresh copy of Microsoft 365.

Run the Microsoft Support and Recovery Assistant for Activation
If a clean reinstallation still fails to activate your subscription, use Microsoft's automated diagnostic tool designed specifically for Office activation errors.

Frequently Asked Questions
Why does my new Microsoft 365 installation show up as Office 2016?
This usually occurs when older license keys, pre-installed trial versions, or cached credentials for Office 2016 are still present in your Windows registry or Credential Manager. The system detects the old key and attempts to use it, overriding your Microsoft 365 Family subscription.
Will uninstalling Office using the SaRA tool delete my documents?
No. The Microsoft Support and Recovery Assistant (SaRA) only uninstalls the Office application files, settings, and license data. Your personal documents, spreadsheets, and files saved locally or on OneDrive remain perfectly safe.
How many devices can I activate with a Microsoft 365 Family plan?
A Microsoft 365 Family subscription can be shared with up to 6 people. Each person can install the Office apps on all their devices and can be signed into 5 devices simultaneously.
What if the SaRA tool cannot fix my activation error?
If the automated tools fail, you may need to manually remove cached Office credentials by opening the Windows 'Credential Manager', navigating to 'Windows Credentials', and deleting any entries containing 'MicrosoftOffice'. If the issue persists, contacting Microsoft Support directly is recommended.
