What Is A “.dll” File?
The “.dll” extension symbolizes that a file is what’s called a “Dynamic Link Library.” These types of files contain libraries with resources that applications require to run properly on your computer.
If a programmer writes code that is useful but doesn’t do anything on its own, yet can be used by other apps to make them work, when they build that code, it comes out as a .dll file, and not a .exe file, as it cannot be run as a standalone app. So, like reusable code that can be accessed by many apps as an extension or a feature, but isn’t an app on its own, like 3D renderers, database engines, and other types of code that an app can “call” for its benefits.
So, for example, if program A has to borrow code and data from library A but that library is corrupt or missing from the system, program A will be unable to start and you’ll get the “Missing Wldcore.dll” Windows error.
This is why .dll files are very important as numerous processes and applications on our computers require them.
The “Missing Wldcore.dll” Windows Error Explained
Now that you know more about “.dll” files, what they’re used for, and how important they are for apps to run properly, or at all, you likely have a much better idea of why the “Missing Wldcore.dll” error appears on your computer.
It’s simple, the apps you’re trying to run require the “Wldcore.dll” library, and your computer doesn’t have it or it’s inaccessible for some reason.
Users reported seeing multiple different messages shown on the error prompt when dealing with this error. Some of the ones we know are:
- Wldcore.dll cannot be found

- Cannot find C:\Windows\System32\wldcore.dll
- Cannot register wldcore.dll
- Wldcore.dll not found
- A required component is missing: wldcore.dll
- Missing wldcore.dll
- Application failed to start because wldcore.dll was not found
Though it seems daunting at first, this problem is not complicated to understand at all. Here’s what you can do to fix it.
Fix 1: “Fetch” The Missing “.dll” From A Functioning Program
One of the easiest ways to fix this issue is by “fetching” the wldcore.dll file from one of the folders of the Windows Live apps that share it, then paste it into the folder of the app that cannot launch due to the file missing from its main folder.
Here’s how to do that:
- Open the Windows File Explorer.
- Navigate to C:\Program Files (x86)\Windows Live\Shared or if you are a 64-bit user, open the “regular” Program Files folder, not the one with the x86 extension to its name, as you may not find the files in the x86 folder (skip this if they’re already there).
- In the Shared folder, you’ll see a list of files. Find wldcore.dll and wldlog.dll, select both, then click copy.
- Now go back one folder in the address, and you should be in the C:\Program Files (x86)\Windows Live location. Open the Messenger, Contacts, and Mail folders, then paste the two files you copied in each of these three folders you just opened.
Now, restart your computer and see if the error still shows up upon trying to open one of the Windows Live programs.
Fix 2: Download The “.dll” File From The Internet
If you cannot seem to find the wldcore.dll file even in the folder mentioned in the section above, you’ll have to re-acquire it from the internet.
Luckily, dll-files is a popular website that serves as a database for .dll files, and you can find the wldcore.dll file there and download it for free.
Simply open the website, type in wldcore.dll in the search bar, and initiate the search by pressing Enter on your keyboard. Then, click on the file from the search results list, scroll down and find the latest version, then click Download.
Wait for the download to complete and then unzip the file. Copy and paste the file into the Messenger, Contacts, and Mail folders mentioned in step #4 in the previous section above.
Now, the problem should be fixed, and you should be able to launch the program(s) without receiving the missing wldcore.dll Windows error.
Fix 3: Run The System File Checker (SFC) Tool In The Command Prompt
Sometimes users don’t manage to fix the problem despite reacquiring and re-adding the wldcore.dll file in the adequate folders. In such cases, the System File Checker tool can help fix the problem, and using it is quite straightforward.
The System File Checker can also help with many other Windows problems related to missing or corrupt files. Here’s how to run it:
- Simultaneously press Windows + S on your keyboard to bring up the Search Box.
- Type in Command Prompt, right-click the first result, and choose Run as Administrator to launch an elevated version required for this fix.
- Once the Command Prompt is open, type in sfc /scannow and press Enter on your keyboard to initiate the command, as shown in the image below.
Wait until the process is complete. You’ll get a confirmation message once it finishes scanning. When the verification and repairs are carried out, restart your PC and check if the problem persists.
For most users, this method solved the problem, so it should work for you too.
That covers everything you should know about fixing the missing wldcore.dll Windows error. Hopefully, the methods listed in this guide will help you restore functionality to the group of Windows Live apps.
Note that this is a relatively common problem amongst Windows users and it doesn’t point out to a more serious problem with your PC or Operating System. It’s only caused by a missing .dll file, as explained in this guide.
