Error Microsoft Office 0x426-0x0 is an error code that appears when you can’t run one of the programs in Office package. This error is common in Outlook, but can affect other Office applications as well. The 0x426-0x0 error usually occurs when users try to run Outlook, Excel, Word or PowerPoint.

It usually takes time to fix this error because the built-in Office recovery feature often does not complete the fix process.

So, if you can’t always rely on the recovery feature, let’s see what else you can do to get rid of the 0x426-0x0 error.

What are the reasons for the 0x426-0x0 error?

Before we get to the solutions, let’s take a look at the reasons for that. Here are some of the most common causes:

  • A corrupted Microsoft Office installation
  • Microsoft Office service click and work disabled
  • Third Party Application Interference
  • Conflict between the old and current version of Office

Temporarily turn off your firewall and antivirus

Error code 0x426-0x0 when installing or upgrading Microsoft Office may occur due to network or firewall restrictions. Network or firewall rules for the network / computer may block the installation of Office software or updates as part of their security measures. These firewall and antivirus rules are implemented by the network provider or computer user in their main system or in the computer registry.

You can fix the 0x426-0x0 error code by temporarily disabling the firewall or antivirus, or you can fix the 0x426-0x0 error by creating an exception rule to install or update Microsoft Office.

Step 1. open the Control Panel.

Step 2: Go to “System and Security”, then “Windows Firewall”.

Step 3: Click Enable or disable Windows Firewall.

Step 4. select Disable Firewall for private and public networks.

Step 5 Try to install or update Microsoft Office and see if the error code 0x426-0x0 has disappeared.

End all Office-related processes in Task Manager

If earlier in the current Windows 10 session the Office processes were running in the background, some of them may block the launch of new Office applications, resulting in 0x426-0x0 error.

The solution is to start the task manager and finish all processes related to Office running in the background mode.

Click the Processes tab to display a list of all active processes. Right-click on the Office processes and select Finish the task.

After all this, restart the problematic Office application and check if error 0x426-0x0 is saved.
