If you already redeemed a product key, you're simply reinstalling the apps, or you know you have an assigned license through work or school, you can skip ahead and go to the section sign in to download and install Microsoft 365 or Office. However, if this is the first time you're installing Microsoft 365 or Office, you may have some steps to do first. Expand the Learn more section below for more info.

If this is the first time you're installing Microsoft 365 or Office, you may have to complete a set of pre-installation steps or you may need to follow different steps than what's shown below. What you do depends on if your copy of Microsoft 365 or Office is a home or a business product and whether or not you have a product key that you still need to redeem, an account already associated with your product, or a pre-assigned license.
Microsoft 365 or Office for home
If you have a home product and it came with a product key*, before installing for the first time (or sharing it if you have Microsoft 365 Family), you need to redeem your product key first.
Go to office.com/setup and sign in with an existing or new Microsoft account and then enter your product key to redeem it*. Redeeming your key is what adds your Microsoft account to Microsoft 365 and you only have to do this once. If you're renewing a Microsoft 365 subscription with a new product key, use the same Microsoft account you previously associated with your expired version subscription.
Tip: Once this is done, anytime you need to install or reinstall Microsoft 365 or Office you can go straight to the next section, Sign in to download Microsoft 365 or Office and select the tab for help to install on a PC or Mac. Be sure to sign in with the same Microsoft account you used to redeem your product key at office.com/setup.
Microsoft 365 for business
If your business subscription plan includes the desktop version of the Microsoft 365 apps you won't see an option to install it unless someone in your organization assigned a license to you.
Learn how to check this in What Microsoft 365 business product or license do I have? or if you're a Microsoft 365 admin responsible for assigning licenses to people in your organization, see Assign licenses to users.
Once you verify you have a license, anytime you need to install or reinstall Microsoft 365 you can go straight to the section below, Sign in to download Office and select the tab for steps to install on a PC or Mac. You'll sign in with your work or school account for these versions of Microsoft 365.
*If you don't have a product key or an account
Some versions of Microsoft 365 such as Office Professional Plus 2021, Office Standard 2021, or a stand-alone app such as Word 2021 or Project 2021 don't have an associated Microsoft account, or work or school account.
The steps to install these versions can be different depending if you got Microsoft 365 through one of the following ways:
Workplace Discount Program:
You bought Microsoft 365 for personal use through your company benefit program and have a product key, see Install Office through the Workplace Discount Program.
Volume license versions:
IT departments might use a different method when installing Microsoft 365 for people in their organization. Talk to your IT department for install help.
Third-party seller:
You bought Microsoft 365 from a third-party and you're having problems with the product key.

The 64-bit version is installed by default unless Microsoft 365 or Office detects you already have a 32-bit version of Microsoft 365 or Office (or a stand-alone app such as Project or Visio) installed. In this case, the 32-bit version of Microsoft 365 or Office will be installed instead.
To change from a 32-bit version to a 64-bit version or vice versa, you need to uninstall Microsoft 365 first (including any stand-alone Microsoft 365 apps you have such as Project of Visio). Once the uninstall is complete, sign in again to www.office.com and select Other install options, choose the language and version you want (64 or 32-bit), and then select Install. (See Install Visio or Install Project if you need to reinstall those stand-alone apps.)

Before you can install Microsoft 365 or Office 2021 you need to associate it with a Microsoft account, or work or school account.
If you have an home product and bought Microsoft 365 or Office at a retail store or online store, but don't have a Microsoft account, it's possible you haven't redeemed your product key yet (if you got one), or you missed the step for linking your recent purchase with an account. Do the following to link an account with Microsoft 365 or Office.
For an Office for home product, go to office.com/setup and create a new Microsoft account or sign in with an existing one, then follow the remaining steps on that page such as entering your product key (if you have one). Your account is successfully associated with Microsoft 365 or Office when you see the page, My Office Account followed by your Microsoft account email address, and a button to install the apps. Select the PC or Mac tabs above to help you with the rest of the install process.
If the Microsoft account or work or school account isn't working, see I forgot the username or password for the account I use with Office.
I don't see an option to install Microsoft 365 or Office after signing in with my work or school account
After signing in with your work or school account you don't see an option to install the desktop applications on the Microsoft 365 home page, go directly to the Microsoft 365 Software page instead. Select the language and bit-version you want (PC users can choose between 32-bit and 64-bit), and then click Install. See Step 2 and 3 on the PC or Mac tabs above to help you with the rest of the install process.
If you still don't see an option to install Microsoft 365 on the Microsoft 365 Software page, it's possible your admin hasn't assigned a license to you. Find out if you have a license to install Microsoft 365.
If you're a student or teacher and your institution didn't give you a license, find out if you're eligible to Get Microsoft 365 for free.
I can't sign in with my work or school accountIf you're trying to sign in with your work or school account to www.office.com and your sign in is blocked, it likely means your Microsoft 365 administrator set up a security policy that's preventing you from signing in to that location.
To install Microsoft 365, try signing in directly to the Microsoft 365 Software page instead. Select the language and bit-version you want (PC users can choose between 32-bit and 64-bit), and then click Install. See Steps 2 and 3 on the PC or Mac tabs above to help you with the rest of the install process.
If you're still not able to sign in, contact your administrator.
