This is an error that may be caused from corrupted downloaded files, to fix that:

  1. Start Run and type regedit
  2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run folder
  3. Delete the Error_access_disabled_by_policy file
  4. Restart then try to reinstall the prerequisites wizard.
