Error code 30174-4, 30125-4, or 30038-4 when installing Office
You might see one of these errors if your antivirus software, firewall, or proxy settings prevent you from installing Office. Here are some things you can try to fix the problem. We’ve listed the most common solutions first, so try them in order.
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.
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.
4 - Temporarily turn off antivirus
If you need information about how to turn off your antivirus software, check your antivirus manufacturer's website. Uninstalling your antivirus software may also help. Don't forget to reinstall it after Office is finished installing!
5 - Temporarily turn off firewall
Turn off Windows Firewall in Windows 8 or Windows 7, or Windows Vista. If you're using a firewall from another manufacturer, visit the manufacturer's website for information about how to temporarily disable the firewall.
