Install Office 2016 on macOS Catalina (10.15)

Steps to download and install a compatible 64-bit build of Office 2016 for macOS Catalina.

macOS Catalina does not support 32-bit applications. To run Office 2016 on Catalina, you must install a 64-bit version (version 15.35 or later). While it is technically possible to run it, remember that Office 2016 no longer receives security or feature updates.

1
Verify your Microsoft account license

Log into your Microsoft account online and navigate to the 'Services & subscriptions' section to ensure your perpetual Office 2016 license is active and tied to your account.

2
Download the 64-bit installer

Locate Office 2016 in your subscriptions list and click 'Install' to download the 64-bit installation package to your Mac.

3
Run the installation process

Open the downloaded .pkg file, follow the on-screen prompts to install the suite, and enter your Mac administrator password when prompted.

4
Launch and authenticate

Open Microsoft Word from your Applications folder, sign in with your Microsoft credentials to activate the software, and begin editing documents offline.

End of Support Warning: Because Office 2016 reached its end of support in October 2020, running it on newer operating systems like Big Sur (macOS 11) is not guaranteed and may result in software crashes or degraded performance.

Frequently Asked Questions

Does Office 2016 work on macOS Big Sur?

While it might launch, Office 2016 is not officially supported on macOS Big Sur (macOS 11). Microsoft ended support for Office 2016 in October 2020, so you may experience performance issues, missing features, or unexpected crashes.

Can I still use Word 2016 offline on Mac?

Yes, if you have successfully installed and activated a 64-bit version of Office 2016 on a compatible macOS version like Catalina, you can continue to use Word and other included applications entirely offline.

Is my Office 2016 perpetual license transferable to a new Mac?

Standalone perpetual licenses are typically tied to the original Mac they were installed on. Depending on your specific license terms, you may not be able to easily transfer a 2016 license to a newly purchased Mac without contacting support.

Why does macOS Catalina require a specific version of Office 2016?

macOS Catalina dropped all support for 32-bit applications. If you have an older 32-bit installer of Office 2016, it will not run. You must ensure you are using a 64-bit build (version 15.35 or newer) to install it on Catalina.
