How to Solve Error Code 0x426A

There are several troubleshooting steps you can take to resolve error code 0x426A:

Run the System File Checker (SFC)

Open Command Prompt as an administrator and run the command sfc /scannow. This tool scans for corrupted system files and attempts to repair them.

Check Disk Space Availability

Ensure your hard drive has enough free space for the installation or update. You can check disk space by opening File Explorer and selecting "This PC."

Run as Administrator

Right-click on the installer file and select "Run as administrator" to ensure you have sufficient permissions.

Disable Antivirus Temporarily

Temporarily disable your antivirus software during the installation process. Remember to re-enable it afterwards.

Perform a Clean Boot

A clean boot starts Windows with minimal drivers and startup programs, which can help isolate potential conflicts. To perform a clean boot:

  1. Search for "System Configuration" in the Start menu.
  2. Open it and navigate to the "Services" tab.
  3. Select "Hide all Microsoft services," then click "Disable all."
  4. Repeat this process on the "Startup" tab.
  5. Restart your computer and attempt the installation again.

Reset Windows Update Components

Open Command Prompt as an administrator and run the following commands sequentially, pressing Enter after each one:

  • net stop wuauserv
  • net stop cryptSvc
  • net stop bits
  • net stop msiserver

Rename the SoftwareDistribution folder to SoftwareDistribution.old by typing: ren C:\Windows\SoftwareDistribution SoftwareDistribution.old

Restart the services using the following commands (again, pressing Enter after each one):

  • net start wuauserv
  • net start cryptSvc
  • net start bits
  • net start msiserver

Repair Windows Installation

If other solutions fail, you may need to consider repairing your Windows installation using the "Repair your computer" option from a bootable Windows installation media.

It's important to note that these are general troubleshooting steps, and the most effective solution will depend on the specific circumstances causing error code 0x426A. If you continue to encounter problems, contacting Microsoft support or consulting with a technical professional may be necessary.
