Download Validation Tool

This solution is for users that are facing the issue due to an MS Office 2007 installation. If during the initial installation you chose file validation, Windows will update other applications but will give Error 0x80240023 for Office 2007. However, the solution is relatively simple. Download the validation tool for Office 2007 and run the file. For this

  1. First, visit the Update Catalog by Microsoft.
    Windows Update Catalog
  2. Then, search for either 2505184 or Microsoft Office File Validation Add-in.
    Microsoft Office File Validation Add-in
  3. Download the Microsoft Office File Validation Add-in file.
    Download File
  4. Extract the file. Then, run the OFV file inside the folder.
  5. After installation run Windows Update again.
  6. The update will now not cause any issues.

Keep the Computer Running

Another well-documented solution from users is to leave the device running overnight. This solution is for users who are not very tech-savvy. The reason for this solution is that instead of downloading the Office File Validation Add-In file, the system will automatically update the File Validation and continue with the updates. The average running time is somewhere between 6 and 12 hours.
