How to Solve Error 0x80072C34

There are several troubleshooting steps you can take to resolve error code 0x80072C34. Try these solutions in order:

Run the Windows Update Troubleshooter

Windows includes a built-in troubleshooter that can often identify and fix common update issues. To access it, go to Settings > Update & Security > Troubleshoot and select Windows Update. Follow the on-screen instructions to run the troubleshooter.

Check for Disk Space

Insufficient disk space is a common culprit behind installation errors. Ensure you have at least 20GB of free space on your system drive (typically C:). To check your disk space, open File Explorer, right-click on your system drive, and select Properties. Look at the "Free space" value.

Disable Antivirus Temporarily

Sometimes antivirus software can mistakenly flag installation files as threats, leading to errors. Try temporarily disabling your antivirus and then attempting the installation again. Remember to re-enable your antivirus once the installation is complete.

Reset Windows Update Components

Resetting the Windows Update components can often resolve update-related issues. To do this:

  1. Open Command Prompt as an administrator (search for "cmd" in the start menu, right-click it, and select "Run as administrator").

  2. Execute the following commands one by one, pressing Enter after each command:

    net stop wuauserv net stop cryptSvc net stop bits net stop msiserver ren C:\Windows\SoftwareDistribution SoftwareDistribution.old ren C:\Windows\System32\catroot2 Catroot2.old net start wuauserv net start cryptSvc net start bits net start msiserver

Run System File Checker

The System File Checker (SFC) tool can scan for and repair corrupted system files. To run SFC, open Command Prompt as an administrator and execute the command: sfc /scannow.

Update Device Drivers

Outdated or incompatible device drivers can sometimes lead to installation errors. Visit the website of your computer or hardware manufacturer to download the latest drivers for your devices.

Perform a Clean Boot

A clean boot starts Windows with a minimal set of drivers and startup programs, helping to isolate any software conflicts. To perform a clean boot:

  1. Press Windows key + R, type "msconfig" and press Enter.
  2. Go to the "Services" tab and check the box for "Hide all Microsoft services".
  3. Click "Disable all"
  4. Go to the "Startup" tab and click "Open Task Manager".
  5. Disable all startup items listed in the Task Manager.
  6. Close Task Manager and click "OK" in the System Configuration window.

Reboot your computer and try the installation again.

Remember to undo these changes after troubleshooting by enabling the disabled services and startup items.
