However, it’s possible to fix this issue, and in today’s guide, we’re going to show you the best ways to do it.
Why does DLL not found exception occur?
This error appears in Visual Studio when developing software. There are several causes, but these are the most common ones:
- Dependencies issues – If the necessary DLL files aren’t in the right location, you’ll encounter this error.
- Missing components – Visual C++ Redistributables are necessary for app development, so make sure you have them on your PC. Keep in mind that issues with them can occur, and a few users reported that they can’t install Microsoft Visual C++ 2015 Redistributable.
- Using the wrong runtime library – Using the wrong runtime library during compilation can result in this and many other errors.
How can I fix DLL not found exception error?
Before you start fixing this error, there are a couple of quick solutions that you can try:

1. Use a dedicated DLL fixer
If you’re getting DLL not found exception error, one way to fix is to download the necessary components, but that’s not always a simple solution.
One way to make this process simpler is by using DLL repair software. Issues with third-party DLLs occur because they aren’t fully compatible with your operating system.
This solution can fix these types of problems, start the application and let it scan your system and it will do the rest automatically.
2. Install Microsoft Visual C++ 2012 Redistributable Package

- Click the Download button.
- Wait for the file to download.
- Once it’s downloaded, run the setup file to install it.
After installing the Redistributable package the issue should be resolved.
3. Use /MT to compile your code
- Navigate to Project properties.
- Next, select C/C++ and choose Code Generation.
- Set the Runtime Library to /MT.
- Save changes and try to compile the code again.
