Let’s review some of the most common DLL errors and go through the process of troubleshooting these irritating issues.

What Is a DLL?

It helps to understand what your error message means before you begin troubleshooting it. DLL stands for Dynamic Link Library. Essentially, these files are a core part of Windows and allow programs to perform a variety of functions without writing them from scratch every time.

For instance, a program might access a DLL when it wants to display a message on the screen The 12 Most Ridiculous Windows Errors of All Time The 12 Most Ridiculous Windows Errors of All Time You probably see plenty of boring Windows error messages every day.

This results in more efficiency for programmers and standardization across Windows.

But when something goes wrong, that DLL file can go missing. And because many programs can share one DLL on your PC (even at the same time), often a DLL error doesn’t indicate a problem with just one app. This is part of what makes troubleshooting a pain.

Common DLL Errors

As you might imagine, some DLLs pop up in error messages more frequently than others. Here are some of the DLLs most known for causing issues.

MSVCP140, MSVCP120, MSVCP110, and MSVCP100

All four of these are different versions (14.0, 10.0, etc.) of the same DLL. MSVC stands for Microsoft Visual C++, an extremely common format for Windows applications.

Chances are that if you open your installed programs list, you’ll see multiple entries labeled Microsoft Visual C++ 20xx Redistributable. Whenever you install a program that needs a particular version of this package, it prompts you to do so or it won’t work.

MSVCR100, MSVCR71

These two DLLs are companions of the above. While the CP in those stands for C++, these files contain libraries in the C programming language. These two numbers are again different versions of the same file, and you likely have multiple versions installed thanks to program compatibility.

Since these are so common, errors often appear when you launch a variety of software.

VCRUNTIME140

The “link” in Dynamic Link Library exists for a reason—here’s another DLL that’s related to the first two. Versions 7 to 13 of the Visual C++ library DLLs used a different name for each version, resulting in the above common files. Starting with version 14, programs using either language have to link to another new DLL. Its name is VCRUNTIME, which changes with each new version.

D3DX9_43

Here’s a DLL with a different root. The DX in this file name refers to Microsoft DirectX, a collection of APIs for running multimedia games and apps. The 43 in the title refers to a specific version, so you may also see this with another number.

Since your computer only uses DirectX for these intensive programs, you’re likely to see this error when starting a video game.

Lame_enc

Lame_enc isn’t an insult to your PC. It refers to the LAME (LAME Ain’t an MP3 Encoder) encoder that allows audio software to convert to MP3. Due to software patents The Death of MP3: A Brief History of the World's Favorite Audio Format The Death of MP3: A Brief History of the World's Favorite Audio Format The German foundation that owns the patent to venerable "old" music format MP3 recently announced that they would let their patent lapse.

NTDLL

Probably the most serious error on the list, NTDLL is a file that handles NT kernel functions. NT used to stand for New Technology and was once a part of the Windows product name, but now is only included in technical Windows information.

Errors about this DLL are often caused by driver issues or a problem with Windows interfacing with a program. Because this file handles low-level system functions, crashes often prevent you from booting into Windows.

Step 0: What Not to Do

When troubleshooting DLL errors, you will almost certainly come across websites claiming they can fix all your problems with a simple download of the DLL file you need. Do not download DLL files from these websites.

Plus, replacing a single DLL is often not enough to fix your issue, which means tracking down a new one is a waste of time.

Also, avoid jumping right to the specific DLL file that causes the error, and don’t dig around in the Windows Registry.

Step 5: Update Relevant Drivers

If the DLL error pops up when you deal with a specific piece of hardware, you should update the appropriate drivers.

Step 8: Re-Register the DLL

At this point, it’s worth trying to unregister and re-register the DLL file. This forces Windows to “forget” the DLL for a moment and re-establishes the component, which can fix the issue.
