How do I download and install Office?

If you're looking for the steps to download and install the latest version of Office, see Install Office on your PC or Mac.

If you want to download and install Office 2013 or Office for Mac 2011, see Install Office 2013 on a PC or Office for Mac 2011.

How do I reinstall Office?

If you're reinstalling Office on a different computer than the one where you originally installed Office, note the following:

  • For Office 365 subscriptions: We recommend you first deactivate the install you don't need anymore and then uninstall it from that PC or Mac. See Deactivate an Office 365 install. Remember, with Office 365 Home, you can install Office on up to 5 PCs or Macs; with Office 365 Personal you can only install Office on 1 PC or 1 Mac; and with Office 365 University you can install on 2 PCs or Macs. Installing Office on more computers than what your plan allows will result in activation and unlicensed product errors.

  • For a one-time purchase of Office 2016 such as Office Home & Student, Office Home & Business, or Office Professional: You can install Office on only 1 PC or Mac. However, you may transfer Office 2016 (or Office 2013) to another computer that belongs to you if you experience a hardware failure or you buy a new computer. For more information, see the Microsoft License Terms for your product, or see this blog post, Office now transferable.

When you're ready to reinstall Office, sign in at https://www.office.com/signin with the same Microsoft account you originally associated with your Office product when you first installed it. You can also find installation steps here:

For the latest version of Office, see Install Office on your PC or Mac.

For Office 2013 or Office for Mac 2011, see Install Office 2013 on a PC or Office for Mac 2011.

Reinstall Office

To reinstall Office, follow the steps in Download and install or reinstall Office on your PC or Mac.

If Office still won't install, check that your computer meets the system requirements to install Office. For example, you can't install Office on computers running Windows XP, Windows Vista, or Chromebooks.

If you're still unable to install Office following the steps in Download and install or reinstall Office 365 or Office 2016 try using the offline installer.

The Office offline installer may help bypass potential proxy, firewall, antivirus, or Internet connection issues that might occur during an Office 2016 installation.

For steps to install an offline version of Office 2016, see Use the Office 2016 offline installer and select the correct tab for your version of Office.

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 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 your computer's browser. See the supported browser section on the system requirements page.

You don't want to install all the Office applications

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.

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.

You want to install Office on a drive other than the C: drive

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

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

You'll get an error if you try to install the 64-bit version of Office and you currently have the 32-bit version installed (or vice versa).

Therefore, if you previously installed the 32-bit version of Office on your PC, but decide you now want the 64-bit version, or vice versa, you'll have to uninstall the bit version you don't want and then reinstall the bit version you do want instead. Use this easy fix to uninstall Office.

You get a KERNEL32.dll error when trying to install Office and other system requirement issues

If you're trying to install Office on a computer running Windows XP or Windows Vista, you may get an error that says the dynamic library KERNEL 32.dll can't be located.

Check that your computer meets the minimum system requirements to install Office. You need a computer running Windows 7, Windows 8, or Windows 10. See System requirements for Office for a list of additional requirements.

If you're not sure which operating system you have, see Which Windows operating system am I running? or Find the OS X version and build number on your Mac.

    Office 365 Subscriptions page

    You’ll see the services that you're licensed to use, such as the latest desktop version of Office, 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 your organization has a plan that includes those applications) your admin probably hasn't assigned an Office license to you. If you're an admin, see Assign licenses to users in Office 365 for business. For more information, see What Office 365 business product or license do I have?

    If you have a license, then you're ready to Install Office on your PC or Mac, (or Project Online Desktop Client or Visio Pro for Office 365).

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 plans that don't include the Office desktop client. If your organization has one of these Office 365 plans, the Office 365 admin can switch to a different Office 365 plan or subscription or buy another Office 365 for business subscription for users in an organization who require the full version of Office.

If you're an admin and you aren't sure what plan you have, follow the steps in What Office 365 for business subscription do I have? For a comparison of plans, see compare small business plans or compare enterprise plans.

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 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 your computer's browser. See the supported browser section on the system requirements page.

If you're trying to install Office on a computer running Windows XP or Windows Vista, you may get an error that says the dynamic library KERNEL 32.dll can't be located. This occurs because Office 2016 and Office 2013 isn't supported on these versions of Windows. For more information, see Why can’t I install Office 2013 or Office 2016 on Windows XP or Windows Vista?

If you're not sure which operating system you have, see Which Windows operating system am I running? or Find the OS X version and build number on your Mac.

If your computer can't install the full desktop version of Office because it doesn't meet the system requirements, you can try using Office Online in your computer's browser.
