Using the offline installer is an effective way to overcome the Office error code 30174-4


Microsoft Office is a handy tool that helps users create professional documents and complete other essential tasks. Many users rely on this fantastic tool, however, many people have been complaining lately about facing an Office error code 30174-4. This error can stop you from installing and using MS Office, making it quite annoying for many users.

This error typically occurs when your firewall, antivirus, or proxy settings are stopping you from installing Microsoft Office. In this guide, we will show some easy steps to quickly resolve this issue.

Try these quick fixes before applying our more comprehensive solutions.

  • Use a cable connection instead of a wireless network to install Office. By doing so, you can increase connection stability and reduce errors. Due to packet loss, wired connections are always more reliable than wireless ones. Reinstall Office after connecting your computer to the router using an Ethernet cable, and check to see whether the issue has been fixed.
  • If the Office installation is failing, your network connection may not be functioning properly, or if you are linked to your work or school’s network, those networks may have network restrictions. We recommend changing your internet provider. If possible, connect your system to a different network connection.

If the step above does not work, try out the solutions below.

1. Temporarily disable antivirus and firewall

A firewall or antivirus program may occasionally interfere with the installation of Office and cause it to fail. Antivirus is raising a false positive that can be disregarded. In such circumstances, you can disable the firewall or antivirus software before installing Microsoft Office. Follow the steps below to do this.

  1. Press Windows + R to open the Run dialogue, type cmd in the text field, then hold Ctrl + Shift + Enter simultaneously to open the command prompt as an administrator.
