Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
To use a Groupon (or other product key) and then download Microsoft 365, first redeem the key and associate it with a Microsoft account, then install the apps.
- Go to https://setup.office.com.
- Create a new Microsoft account or sign in with an existing one.
- Follow the steps on that page to enter and redeem the product key (the Groupon code). When the account is successfully associated, a page appears showing My Office Account with the Microsoft account email address and an Install button.
- After redemption, on the same page select the PC or Mac option as appropriate and follow the install steps.
- Alternatively, sign in at https://m365.cloud.microsoft/apps (or https://www.office.com as described in the Q&A) with the same Microsoft account, go to Apps, then choose Install apps to download the installer. Run the downloaded file to install Microsoft 365 on the computer.
If this is a subscription (for home), once the key is redeemed and linked to the account, Microsoft 365 can be installed on any supported PC or Mac by signing in with that account and selecting Install from the Apps page.
