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 for Mac, and then restart the Office installation.

If you're installing Office on a PC (desktop, laptop, or 2-in-1), try these solutions in the order listed.

1. Does Office hang or freeze at 90%?

If your Office installation hangs or freezes at the 90% mark as shown in the screen capture below, this could be because the Windows Installer is busy. For a possible solution, see Installation of Office hangs at 90%.

2. 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.

3. 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.

4. If you're on a slow internet connection, install Office 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 installation.

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

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