Solution 1Recommended

Clean Install Office 2016 via Microsoft Services and Subscriptions

Completely remove any remaining Microsoft 365 trial or subscription files, deactivate previous licenses, and install your official copy of Office 2016.

Microsoft 365 and standalone versions like Office 2016 often use different installer technologies (Click-to-Run vs MSI). Leftover files from Microsoft 365 can block the installation of Office 2016. A clean download from your account dashboard ensures you get the correct version tied to your license.

1
Verify Microsoft 365 is completely uninstalled

Go to Windows 11 Settings > Apps > Installed apps. Search for 'Microsoft 365' or 'Office'. If any pre-installed trials or apps are listed, click the three dots next to them and select 'Uninstall'.

2
Sign in to your Microsoft Account

Open a web browser and go to account.microsoft.com. Sign in with the exact Microsoft account credentials you used to purchase or register Office 2016.

3
Navigate to Services & subscriptions

Click on the 'Services & subscriptions' tab at the top of the dashboard page. Scroll down to locate your 'Office 2016' product under the 'Products you've purchased' section.

4
Deactivate old installations (if applicable)

If you are moving Office 2016 from an old PC to this Windows 11 PC, click 'Install' and look for an option to 'Deactivate' an existing installation on another device to free up your license.

5
Download and install Office 2016

Click the 'Install' button next to Office 2016 to download the setup executable. Once downloaded, double-click the file and follow the on-screen prompts to complete the installation.

Use Microsoft Support and Recovery Assistant: If the Office 2016 installer still fails, download the Microsoft Support and Recovery Assistant (SaRA) tool to scrub hidden registry entries and residual files left behind by Microsoft 365.

Frequently Asked Questions

Why does my Office 2016 installation fail even after uninstalling Microsoft 365?

Standard uninstallation via Windows Settings sometimes leaves behind registry keys and licensing background services. These remnants can trick the Windows installer into thinking a newer version of Office is still present, blocking the Office 2016 setup.

Can I have both Microsoft 365 and Office 2016 installed on Windows 11 at the same time?

Generally, no. Microsoft restricts installing different versions of Office that use the same installation technology (like Click-to-Run) on the same computer to prevent application conflicts and licensing issues.

Where can I find the official download link for my purchased Office 2016?

You can download it securely by logging into your Microsoft account online, navigating to the 'Services & subscriptions' tab, and finding Office 2016 under your purchased products list.

Will my old Word and Excel files be deleted if I uninstall Microsoft 365?

No. Uninstalling Microsoft 365 only removes the application software from your device. Your locally saved documents, spreadsheets, and presentations remain completely intact and will open automatically once Office 2016 is installed.
