5 Easy Ways to Fix the “libxess.dll” Error in Windows [2024]

Key Takeaways
  • Dynamic Link Libraries (DLLs) are files containing code and data used by multiple programs on Windows. For example, comdlg32.dll handles dialog boxes in Windows.
  • DLL files often crash due to modifications, malware infections, or accidental deletions, leading to errors like "libxess.dll missing."
  • Check system compatibility with Intel XeSS SDK, update XeSS SDK, verify file integrity, reinstall XeSS SDK, or contact Intel support for assistance.

When you are using software or playing games on Windows, especially older versions, you probably have been hit with a DLL issue like “libxess.dll missing.” Usually, when you come across an individual DLL issue it’s only telling you a part of the story. That is why in this article, we will help you with everything you need to know to fix the libxess.dll error and get your system running back again. So let’s jump in!

What does comdlg32.dll mean?

What Are .DLL Files?

DLL stands for Dynamic Link Library and is a type of file that contains code or in other words, instructions that other programs can use to perform certain tasks. The reason they are called libraries is that DLLs are like digital books that can be accessed by multiple programs at the same time. Once a DLL is loaded into memory, any program can request access without the DLL having to be loaded over and over again.

A good simple example of this is the “comdlg32.dll” file which contains the code for bringing up a Windows popup dialog box. Since so many programs use this functionality it makes sense for this code to be included in Windows as a DLL instead of writing it into every program from scratch.

Why Are DLL Files Always Crashing?

While DLLs are quite important considering how helpful they are, they are also the reason behind several problems referred to as “DLL HELL.” One reason why DLLs often crash is due to modification. This means that if a DLL file gets modified and the newer version isn’t compatible with all the other programs that rely on it, it will simply crash.

For instance, an installer may decide to modify a DLL in a way that helps that specific application but can cause errors in other programs that need the same DLL but aren’t compatible with the modified version. Apart from that other factors like malware infection, corrupted DLL files or accidental deletion can also cause DLL issues.

Intel XeSS Super Sampling

What is Intel XeSS?

Intel XeSS also called Intel Xe Super Sampling is Intel’s response to Nvidia’s DLSS and AMD’s FSR upscaling technology. It works by rendering frames at low resolutions and upscaling them to bigger resolutions without losing image quality.

This allows you to play games at lower resolutions for smoother gameplay and still get high-quality visuals, or produce higher-resolution images without sacrificing frame rates.

Intel XeSS has two versions: one is open-sourced and compatible with any graphics card that supports DP4A instructions. The other one is exclusive to Intel cards as it takes the use of Intel’s XMX units to perform its magic.

How To Fix libxess.dll Error

Now that we know what the libxess.dll is and what it’s related to, it’s time to fix it. As the libxess.dll error is related to Intel XeSS SDK, it may indicate an issue with the software. To fix that, here are some troubleshooting errors that you can take:

1. Check System Compatibility

Before trying out the other troubleshooting steps, the first thing you should check is whether your system is compatible with XeSS SDK or not. You can head to Intel’s website and match the recommended system specifications with what you have and if they both don’t match it’s time to upgrade a few things.

2. Update XeSS SDK

One of the common reasons for libxess.dll not working is using a downgraded version of the XeSS SDK. To fix that, you can head to the official website and check if there’s a latest version available to download. Upgrading XeSS SDK to the latest build can fix underlying issues, improve overall performance, and resolve DLL errors.

3. Verify File Integrity

A corrupted or damaged libxess.dll file can also cause improper functioning. To check if your file is working as it should, you’ll need to compare the hash value of your DLL file with the official hash value provided by Intel.

A hash value is a unique alphanumeric string generated by a hash function, representing the original data. It’s used for data integrity checks, indexing, security (e.g., digital signatures, password hashing), and efficient data comparison. Hash values are fixed in size and play a crucial role in various computer science applications

4. Reinstall XeSS SDK

If the hash values don’t match, we recommend reinstalling the Intel XeSS SDK. You will first need to uninstall the existing XeSS SDK from your computer and then download the latest version from Intel’s website. This way you’ll have a fresh new installation of XeSS SDK removing any bug fixes and issues related to libxess.dll or its dependencies.

Before reinstalling XeSS SDK, make sure to save your configuration settings as this will allow you to restore your system if things go south.

Should You Install Standalone DLL Files?

Several websites claim to provide standalone DLL files like libxess.dll that sound like just the answer you need to fix your issue. However, there is no guarantee that these files are safe and will work on your computer. You see, developers create DLL files as part of their software packages, and they can only guarantee a stable working file.

This means that websites offering single DLLs might look authentic but they are not approved sites for downloading DLLs and often provide little to no contact information in cases of any virus infections. Another problem with downloading single file fixes is that they might fix your issue at first but later on they tend to cause additional missing DLL issues.
