What Is A “.dll” File?

Problem

The file extension “.dll” indicates that a file is a “Dynamic Link Library.” These files comprise libraries with resources that applications require for seamless operation on your computer.

If a programmer writes code that is beneficial but doesn’t perform any tasks independently, yet can be utilized by other apps to enable their functionality, when they compile that code, it emerges as a .dll file, and not a .exe file, as it cannot be executed as a standalone app. So, similar to 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 forms of code that an app can “call” for its advantages.

Folder

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:

  1. Open the Windows File Explorer.
  2. Navigate to C:Program Files (x86)Windows LiveShared 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).
  3. In the Shared folder, you’ll see a list of files. Find wldcore.dll and wldlog.dll, select both, then click copy.
  4. 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

Download

If you’re unable to locate the wldcore.dll file in the folder mentioned earlier, you’ll need to obtain it again from the internet.

Fortunately, dll-files is a well-liked website that serves as a database for .dll files, and you can find the wldcore.dll file there and download it for free.

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.
