Chromebooks, and computers running Windows Vista or Windows XP don't meet system requirements to install Office

You can't install Office 2016 or Office 2013 on Chromebooks, or computers running Windows Vista or Windows XP as these operating systems don't meet the system requirements for Office. Attempting to install Office on a computer running an unsupported operating system will result in an error. (If you're interested in learning more about the latest version of Windows, see Windows 10 specifications for details.)

If your computer can't install the full desktop version of Office because your computer doesn't meet the system requirements, you can try using Office Online in Office 365 in your computer's browser. See the supported browser section on the system requirements page.

You don't want to install all the Office applications and/or you want to install Office on a different drive

When you install Office 2016 or Office 2013, all the applications that came with your particular Office product is installed at the same time. You can’t custom select which Office applications you want to install or not install, nor you can't delete individual applications after your installation is complete. However, you can delete shortcuts to applications you don’t plan to use.

You can only install Office on the system drive where your operating system is installed. That’s usually your C: drive.

Tip: If you discover you need an application that didn't come with your Office product, you have the option to purchase a stand-alone application. For example, you may decide you need Access or Outlook, but those applications weren't included in your product. To purchase a stand-alone application, go to https://products.office.com/ and do a search for the app you want to buy.

Install the 64-bit version of Office instead of the 32-bit version

If you previously installed the 32-bit version, but decide you now want the 64-bit version, you'll have to uninstall 32-bit and then reinstall the 64-bit version of Office. See Choose the 64-bit or 32-bit version of Office 2016.

I get a "Stop, you should wait to install Office 2016" error

Office 2016, cannot coexist on the same computer with certain standalone Office 2013 applications. This includes any Office 2016 product whether part of an Office 365 subscription or purchased as a suite of applications such as Office Professional 2016, Office Home and Student 2016, or Office Home and Business 2016. For example, if you have a standalone 2013 app (such as Word 2013) installed on your computer, a newer version of the app is already included in the Office 2016 suite you're trying to install. Therefore, the standalone version of Word 2013 will be removed if you choose Install Anyway. You won’t be able to reinstall the standalone 2013 app again on the same computer.

If you're on Deferred Channel, older versions of some standalone Office products, such as Project 2013 or Visio 2013, aren't compatible with Office 2016. After February 2017, side-by-side installs of Deferred Channel with any standalone 2013 applications not included in your Office 2016 install will be supported. See "Stop, you should wait to install Office 2016" error for more information.

If you have Office 2013 standalone apps that are incompatible with Office 2016, you may want to stay on Office 2016 and take advantage of the Special offer for customers with Office 2016 and Office 2013 standalone applications.

If you connect to an Exchange 2007 mailbox, you might want to stay on Office 2013 or even uninstall Office 2016 and reinstall Office 2013.

Where do I install Office for Mac?

I'm an admin and don't have an option to install Office, Project, or Visio

When you first sign up for Office 365 for business and you try to install Office (or Project or Visio if you've also signed up for a plan that includes those apps) you might see a message that says you can't install Office because you don't have a license. This could happen because of a delay between your initial sign in and Office 365 for business setting up your environment. Try signing out of Office 365 and then signing back in.

It could also happen because you haven't assigned a license to yourself or your users. Do the following to check your licenses.

Check that you have a license
  1. If you're not already signed in, go to http://portal.office.com and sign in with your work or school account.

    Note: If you're unable to sign in with your work or school account, you may be signing in to the wrong Office 365 service, see Where to sign in to Office 365.

  2. From the browser header, go to Settings Settings: update your profile, install software and connect it to the cloud > My app settings > Office 365.

    Office 365 Settings pane

    Office 365 Subscriptions page

    You’ll see the services that you're licensed to use, such as the latest desktop version of Office, Project, Visio, SharePoint Online or OneDrive for Business, and Exchange Online. If you don't see The latest desktop version of Office in the list (or Project or Visio if you bought plans with those applications), see Assign or unassign licenses for Office 365 for business.

Not all Office 365 subscription plans come with the fully installed Office applications. See the bottom of the Office for business column for a list of those plans that don't include an installed version of Office. If your organization has one of these Office 365 plans, as the admin, you can switch to a different Office 365 plan or subscription, or in addition to the subscription you already have, buy another Office 365 for business subscription for those users who require the full version of Office.

If you're not sure what plan you have, follow the steps in What Office 365 for business subscription do I have? For a comparison of plans, see Office for business.
