If the above method hasn’t worked, then maybe you need to re-install a fresh copy of iTunes. iTunes is distributed through Apple’s own official website and there’s no need to grab an installer from any third party website.

  1. Uninstall the current iTunes version and download the latest version.
  2. Once downloaded, double click on the executable file. If any confirmation prompt appears, confirm and approve the installation.
  3. Once installed, the iTunes software will ask for your Apple ID and password.
  4. After the username and password are given, the software will be ready for use.

If iTunes still doesn’t work, apparently some Windows core component file required to run iTunes has been damaged.

Conclusion: If none of the above methods seem to work, the only available method is apparently reinstalling a fresh copy of Windows OS as repairing the corrupted registry entries and components one by one would be a hectic process.
