DLL errors are some of the most common, frustrating, and complicated errors to troubleshoot and resolve. Fixing a DLL error is rarely as easy as replacing the DLL, something that we don't recommend doing even if it does fix the problem.

Below is a list of the most common DLL errors that computer users are seeing right now, with links to easy to follow, step-by-step solutions that anyone can handle.

If your DLL error isn't listed below, either follow our general troubleshooting guide for DLL errors or do a search for the error at the top of this page.

D3dx9_43.dll (D3dx9_43.dll Not Found)

"D3dx9_43.dll Not Found" and "D3dx9_43.dll is Missing" errors are usually caused by DirectX problems. You'll most often see d3dx9_43.dll errors when starting certain video games or advanced graphics programs.

Xinput1_3.dll (Xinput1_3.dll is Missing)

Xinput1_3.dl errors are similar to d3dx9_43.dll errors, which we talked about above. Fixing this issue usually involves reinstalling DirectX or updating video, sound, or game drivers.

Hal.dll (Missing Or Corrupt Hal.dll)

The error "Missing or corrupt hal.dll" and other hal.dll errors like it are often caused by boot.ini or hal.dll file issues. This error message usually appears in this way:

Windows could not start because the following file is missing or corrupt - Windows root\system32\hal.dll. Please re-install a copy of the above file.

Kernel32.dll (Invalid Page Fault in Module Kernel32.dll)

"Explorer caused an invalid page fault in module Kernel32.DLL" is the most common kernel32.dll error message you'll see. Kernel32.dll errors are usually caused by software programs that are accessing areas of your system memory incorrectly.

Ntdll.dll (Unknown Hard Error Ntdll.dll)

In almost all cases, ntdll.dll errors are caused by software programs, not the operating system. Common error messages include these and others:

STOP: C0000221 unknown hard error \SystemRoot\System32\n

Ieframe.dll (Res://ieframe.dll/dnserror.htm#)

Ieframe.dll errors can be caused by many different underlying issues. They're usually seen one of two ways:


Vcruntime140.dll (Vcruntime140.dll is Missing)

"Vcruntime140.dll Is Missing" errors almost always happen when trying to start a software program that needs vcruntime140.dll but the program can't find it. One fix is to reinstall the application that's throwing the error, but you can also download and install a program from Microsoft that supplies this DLL file: Visual C++ Redistributable for Visual Studio 2015.

"Error in Loading DLL"

Unlike the other DLL errors on this page, this one is much more generic. You might see this DLL error when trying to start wizards in the Microsoft Office Access program, like Import Wizards or Report Wizard.

Missing Windows Registry keys related to acedao.dll and/or dao360.dll are most likely responsible for this DLL error. Microsoft provides detailed instructions on how to fix "Error in loading DLL" error messages on their site.

This DLL error might also be accompanied with one that reads "Object library not registered."

Msvcp140.dll (Msvcp140.dll is Missing)

Msvcp140.dll errors are similar to other "msvcp" DLL errors such as Msvcp100.dll Not Found and Msvcp110.dll Not Found errors. The fix for those DLL errors and this one is to re-supply the computer with the correct DLL file, in this case msvcp140.dll.

For the msvcp40.dll error specifically, you want to download and install Visual C++ Redistributable for Visual Studio 2015, a software package provided by Microsoft.
