Ntdll.dll error messages can apply to almost any Windows software program, driver or plug-in on all Microsoft operating systems, from Windows NT to Windows 10, Windows 8, Windows 7, Windows Vista and Windows XP.

Restart your computer. The ntdll.dll error you are receiving may be the result of a one-time, temporary problem, and a simple restart may resolve the issue entirely.

If the error only occurs when using a specific program, reinstall the program.

If there are any updates or service packs available for the software program, install them as well. The software's programmers may have identified a problem with the program that was causing the DLL error and then released a patch for it.
