This article explains how to download and install Microsoft 365 or Office 2019 on a Windows or Mac laptop, computer, or tablet.

After purchasing Microsoft Office, activate and download the product. Detailed instructions are included in the packaging if you purchase the software in a store or order a keycard online from, for example, Amazon. If you order directly from Microsoft, you will receive the link in an email. There is an 'Install Office' link on the receipt.

Go to setup.office.com and sign in with your Microsoft account or create a new account.

Enter your product key (or activation code). This product key lets Microsoft know that the software was purchased legally. The key is included with any physical packaging you receive, and is included in an email if you ordered digitally. Also select your country or region and language.
