This step-by-step guide shows you how to download Office 2016 for Mac, install it on your Mac, and activate it with your product key. Whether you just purchased your license or are reinstalling on a new Mac, you’ll be up and running in minutes.

Microsoft Office 2016 Home & Business for Mac is a one-time purchase (perpetual license) that installs the classic desktop apps — Word, Excel, PowerPoint and Outlook — on one Mac, with no Microsoft 365 subscription required.

Office 2016 for Mac system requirements

Before you download Office 2016 for Mac, make sure your Mac meets Microsoft’s minimum requirements:

What you need before you start

• Your 25-character office 2016 for mac product key (delivered by Kymakers to your email after purchase).
• A free Microsoft account — you’ll link your license to this account so you can re-download Office anytime.
• A stable internet connection.
• Administrator access on your Mac (to run the installer).

Step 1 — Redeem your product key at setup.office.com

Microsoft ties your license to a Microsoft account before you can download. Here’s how:

1. Open your browser and go to setup.office.com (or office.com/setup).
2. Sign in with your Microsoft account, or click Create a new account if you don’t have one.
3. Enter your 25-character product key exactly as it appears in your Kymakers email, then choose your country and language.
4. Click Next / Redeem. Office is now linked to your account and appears in your Services & subscriptions at account.microsoft.com.

Step 2 — Download the Office for Mac installer

1. Go to account.microsoft.com and sign in with the same Microsoft account.
2. Open Services & subscriptions and find Microsoft Office 2016 Home & Business for Mac.
3. Click Install (or Download). A file named Microsoft_Office_Installer.pkg downloads to your Downloads folder.

Step 3 — Install Office 2016 for Mac on your Mac

1. Open Finder → Downloads and double-click Microsoft_Office_Installer.pkg.
2. On the installer welcome screen, click Continue.
3. Review the software licence agreement and click Continue, then Agree.
4. Choose the install location (the default is fine) and click Install.
5. Enter your Mac’s administrator password when prompted and click Install Software.
6. Wait for the installation to finish (a few minutes), then click Close.

The Office apps — Word, Excel, PowerPoint and Outlook — are now in your Applications folder and Launchpad.

Step 4 — Activate Office

1. Open any Office app, for example Microsoft Word, from Launchpad or the Applications folder.
2. On the What’s New screen, click Get Started.
3. Click Sign In and enter the Microsoft account you used to redeem your key in Step 1.
4. Office verifies your license automatically and activates. You’ll see your name and account in the app.

Troubleshooting

“This product key has already been used”

Each Office 2016 for Mac key activates one Mac. If you’re moving to a new Mac, sign in with the same Microsoft account you originally used — no need to re-enter the key. If you bought from Kymakers and see this error on a first install, contact our 24/7 support for a replacement.

Office apps ask you to sign in every time

Sign in once fully (Step 4), then quit and reopen the app. If it persists, go to Finder → Applications → Utilities → Keychain Access, search for Microsoft Office Identities Cache, delete those entries, then sign in again.

The installer won’t open (“unidentified developer”)

Right-click the .pkg file and choose Open, then confirm. The Microsoft installer is signed, so this only appears if the download was interrupted — re-download if needed.

Older Office version already installed

You can install this version alongside or after removing the old one. To fully remove an old copy, drag the Office apps from Applications to the Trash, then empty the Trash before installing.
