- If the ntdll.dll error only displays when you use Copernic Desktop Search, uninstall our software, reboot your computer, and then install the latest version again from scratch.
- Selectively disable Internet Explorer add-ons. If your ntdll.dll error is displaying when you start, run, or close Internet Explorer, an add-on may be causing the problem. Disabling each add-on, one by one, will determine which add-on is the culprit (if any).
- Perform a repair installation of Windows XP. If individual software reinstallations fail to resolve the problem, a repair installation of Windows will replace the ntdll.dll file. Remember to install all Windows service packs and other patches after this installation.
- Ntdll.dll errors could occur if you have an Iomega Zip drive on the same IDE cable as the hard drive inside your computer. If so, move the Zip drive to a dedicated IDE controller.
