Office for a small team or household

The 5PC key is meant for several computers that need the same Office: a small office, a family, or a desktop and a laptop plus a few spares.

• Install Office 2021 Professional Plus on each PC and activate it online with the same key, up to five times.
• Every PC gets the full Professional Plus set, including Access for databases and Publisher for flyers and newsletters.
• Files open on any of the five PCs and on other Office versions, so a team can share documents without converting them.

For a single PC, the Office 2021 Professional Plus key costs less.

How to install and activate Office 2021 Professional Plus

Use the same key on each of the five PCs:

1. Install Office 2021 Professional Plus with the guide in your order email. It shows two ways: redeem your key at setup.office.com and download Office there, or download Microsoft’s installation file directly.
2. Open Word or another Office app. If Office asks for a product key, enter the 25-character key from your order email.
3. When the Activation Wizard opens, select I want to activate the software over the Internet, then Next.

Remove any other Office version first, so the two don’t conflict. Full walkthrough: Office 2021 Professional Plus installation and activation guide.
