Solution 1Recommended

Completely Uninstall Previous Microsoft 365 and Office Versions

Removing old Microsoft 365 installations resolves underlying licensing conflicts that prevent the Office 2021 activation wizard from launching.

When Microsoft 365 is previously installed on your device, its hidden license files can override the standard activation prompts for standalone versions like Office 2021. A standard uninstallation often leaves these files behind, requiring a dedicated removal tool.

1
Download the Uninstall Support Tool

Download the official Microsoft Support and Recovery Assistant (SaRA) or the Office uninstall support tool directly from the Microsoft website.

2
Run the Uninstall Tool

Launch the downloaded tool, select Microsoft 365 and any other existing Office versions from the list, and follow the on-screen prompts to completely remove them from your system.

3
Restart and Reinstall

Restart your computer to clear any cached data, then run your Office 2021 installer (offline or online setup) to reinstall the software from scratch.

4
Launch and Activate

Open any Office 2021 application, such as Word or Excel. The activation wizard should now appear normally, allowing you to proceed with internet or telephone activation.

Completely Uninstall Previous Microsoft 365 and Office Versions
Clean Installation: Using the official Microsoft uninstall tool ensures all residual registry keys and conflicting license files from previous Office versions are completely removed.

Frequently Asked Questions

Why does my Office 2021 ask for a product code instead of showing the activation wizard?

This usually happens if remnants of a previous Microsoft 365 installation are still on your system. These lingering files cause licensing conflicts that bypass the standard Office 2021 activation wizard.

Can I run Microsoft 365 and Office 2021 on the same computer?

No, Microsoft generally does not support running different versions of Office (like a Microsoft 365 subscription and a perpetual Office 2021 license) simultaneously on the same device using the same installer technology. You must completely uninstall one before installing the other.

How do I force the telephone activation wizard to appear in Office 2021?

You can often trigger the telephone activation wizard by disconnecting your computer from the internet before launching an Office application. The system will fail to activate online and prompt you with the option to activate by telephone instead.

What should I do if the standard Windows uninstaller doesn't fix the activation issue?

Use the official Microsoft Support and Recovery Assistant (SaRA) tool. It performs a deep clean of your system, removing hidden registry keys and license files that the standard Control Panel uninstaller typically leaves behind.
