How do I download Microsoft 365 to my computer?

Before you begin, make sure your PC or Mac meets the system requirements.

If you are reinstalling Microsoft 365, you have already redeemed a product key, or you are installing Microsoft 365 at work or school and know you have a license, then go to the section sign in to download and install Office.

However, if this is the first time you're installing Microsoft 365, you may have some pre-installation steps to do first. Visit Microsoft's Website for more detailed instructions for installing Office on your computer (Windows or a Mac)
