Error code 30174-4 when installing Office

Not installing Office over the Internet? If you're trying to install Office from a DVD or downloaded file, we have another solution that might work for you.

1 - 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.

2 - 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.

3 - Temporarily turn off proxy settings

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

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

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.
