This error code 30034-4 can become quite frustrating as the obvious fix of uninstalling all instances of Microsoft Office and reinstalling will strangely sometimes not resolve the issue but I recommend trying this as a first step for troubleshooting.

Step 1. – Reinstall Office Installation

As I have just mentioned. It has been found that this step may not resolve the issue but due to the nature of the error code 30034-4 will be recommended the first step you should undertake. After you uninstall your previous versions of MS Office it is important to ensure that you remove anything left behind before you begin the fresh install of Microsoft office.

Delete the Office files

  • Then Delete the Office key.

Step 2. – Temporarily disable Firewall and Antivirus

Error code 30034-4 can also be caused while installing or updating the Microsoft Office by a Network or firewall restriction. The network rules or firewall rules in the network/computer may block the installation of Office program or its updating as a part of their security measurements. You could fix the error code by disabling the firewall or antivirus temporarily or you could fix the error code 30034-4 by making creating an exceptional rule for Microsoft Office installation or update

Follow these steps to disable Firewall:

Customize settings for windows firewall

Step 1. Open “control panel”

Step 2. Navigate to “system and security” and then to “Windows Firewall”

Step 3. Click on “turn windows firewall On or Off”

Step 4. Select Turn Off firewall for both private and public network.

Step 3. Run DISM and System File Checker  

Error code 30034-4 can also occur due to the corruption of system files This can be fixed easily by running the SFC scan. The SFC scan or system file checking scan is the process of replacing or repairing the corrupted copy of system files using the cached copy of the file from the directory.

  • Open Command Prompt as an administrator.
  • Run command: sfc/scannow
Run sfc/scannow on command prompt

It will run the System File Checker.

Run Command – DISM /Online /Cleanup-Image /RestoreHealth
