Error code 30174-4 when installing Office

1 - 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 2016 installation.

How you use the offline installer depends on which Office product you have. See Office for home and Office for business plans and then select from the table below.

Office product

Do this

Your Office product is under Office for home

Use the Office 2016 offline installer

Your Office product is under Office for business

Contact your admin. If you're the admin, you can use the Office Deployment Tool to download the Office software to your local network. You can then deploy Office by using the software deployment method you typically use.

As an admin, you can also Contact Office 365 for business support for additional help.

2 - Use a wired connection

If you aren’t already using a wired connection to the Internet, plug your device in and try installing Office again.

3 - Try installing from another location

If you're trying to install at work or at school, the network may be limited in a way that won't allow Office to install. If this is the case, take your device home, to a friend’s house, or to a wireless hotspot, and then try installing Office again.

Note: If you need to install Office from work or school, your IT department might be able to help you deal with any network limitations.

4 - Temporarily turn off proxy settings

If you use your device both at home and at work, try turning off the proxy settings in Microsoft Edge or Internet Explorer before you install Office. If you’re using a different browser, check their help to find out how to turn off proxy settings.

  3. Clear the checkbox to turn off any proxy settings.

  4. Click OK.

Internet Explorer 7, 8, 9, 10, or 11

Note: There might be more proxy settings that you need to bypass. If this doesn't work, and you’re installing Office from work or school, check with your IT department for more information. For IT administrators, please see Office 365 URLs and IP address ranges.
