For possible solutions, select from below what type of computer you're trying to install Office on.

Are you trying to install Office on a Mac?

If you're trying to install Office on a Mac, follow the steps in Uninstall Office 2011 from a Mac or Uninstall Office 2016 for Mac, and then restart the Office installation.

Are you trying to install Office on a PC (desktop, laptop, or 2-in-1)?

Try these possible solutions in the order listed.

Restart your computer and check if Office installed

The Office installation may have completed. So, after you've restarted your computer, go to Can't find Office applications in Windows 10, Windows 8, or Windows 7? to see if Office actually did install.

Use a wired connection

If Office did not install, try to reinstall after switching to a wired connection. This can help speed up the installation because a wired connection is usually faster than a wireless one. After that, restart the Office installation.

Install Office using the offline installer

Note: If you use Office 365 for business, contact your admin if you believe you need to use an offline installer to install Office. If you're the admin Contact Office 365 for business support - Admin Help.

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

See Use the Office 2016 offline installer and select the offline installer for your Office version. Follow the steps for either Office 365 Home, Personal, or University, or for a one-time purchase of Office such as Office Home & Student or Office Home & Business.

If Office still isn't installing, try some of the options below.
