If your install wasn't successful, see the Additional information section to help you troubleshoot.

Step 1 - Associate Office with a Microsoft account

Before you install your copy of Office for the first time, you need to redeem it (if your copy with a product redemption key) and then associate it with a Microsoft account. How you complete this step depends on how you got your copy of Office. Select from below:

I have a product redemption key for a physical copy of Office got from a retail (storefront) or online store

Physical copies of Office come with a product redemption key. You need to redeem this key, and then associate your copy of Office to a Microsoft account before you can install it on your PC.

Note   The steps below assume you're about to install this copy of Office for the first time. If you already redeemed your key and this is a reinstall or you want to install Office on another computer, go directly to Step 2 - Install or reinstall Office.

An Office product redemption key uses a combination of 25 letters and numbers and looks like this:

Step 2 - Install or reinstall Office from My Office Account

Follow these steps to install Office on your computer for the first time, install Office on a second computer (if you have that option), or reinstall Office.

  • Remember, if you're the owner of an Office 365 Home subscription you can install Office on up to 5 PCs or Macs. You can share your other four installs with friends or family, or use the same Microsoft account to install Office on your other computers. The steps to install are the same.

  • If you have a one-time purchase of Office 2016 or Office 2013 such as Office Home & Student, Office Home & Business, or Office Professional, you can install Office on only one computer. Certain conditions apply if you need to transfer the license. Consult the Microsoft License Terms for your product.

Note   The following steps assume you've already redeemed your product key (if one came with your copy of Office), and that you associated Office with a Microsoft account. If you haven't already done that, go to Step 1 - Before installing you need to associate Office with a Microsoft account.

Sign out and then resign in with the Microsoft account associated with your Office 365 subscription or your copy of Office 2016 or Office 2013. This is the account you used when you set up Office in Step 1 - First time install: redeem Office and associate it with a Microsoft account.

  2. In the Install Information section, select Install.

    By default, this will install the 32-bit version of Office on your PC using the language you selected when you redeemed the product. If you want to install the 64-bit version, change your language, or choose other options, see the section below, Custom install options.
