How to install Office 2024 Home (PC & Mac)

By /

This guide shows you how to install and activate Microsoft Office 2024 Home (PC & Mac). This edition is linked to your Microsoft account when you redeem the key, so you can reinstall it later on the same device by signing in.

Prefer that we do it for you? With Remote Assistance, we connect to your computer with your permission and install and activate Office for you.

1. Remove older versions of Office

Uninstall any Microsoft 365 or older Office version first, including trial versions that came with a new computer. Your documents and emails are not deleted. See How to uninstall an older Office version.

2. Redeem your key with your Microsoft account

  1. Go to Microsoft’s official Office setup page: setup.office.com.
  2. Sign in with your Microsoft account, or create one. See How to create a Microsoft account.
  3. Enter the 25-character key from your Keymsnio order email and follow the steps. The license is now linked to your account.

Make a note of which Microsoft account you used: you’ll need it whenever you reinstall Office.

3. Download and install Office

  1. Go to account.microsoft.com/services and sign in with the same account.
  2. Find Office Home 2024 in the list and choose Install.
  3. On Windows, open the downloaded file and wait for the installation to finish. On a Mac, open the downloaded package and follow the installer.

4. Activate Office

  1. Open Word.
  2. When asked, sign in with the same Microsoft account. Office activates automatically.
  3. To check: on Windows, go to File → Account, which should say Product Activated. On a Mac, open Word and choose Word → About Microsoft Word to see your license.

Troubleshooting

  • “This key has already been used”: if you redeemed it before, you don’t need to enter it again. Sign in at account.microsoft.com/services and install Office from there.
  • Office isn’t listed in your account: check that you’re signed in with the account you used to redeem the key.
  • Installation or activation problems: see Office installation problems and Office activation error, or contact us with your order number and a screenshot.
