Mss32.dll is a file that belongs to the Miles Sound System Library, which is an integral component used in multimedia programs such as Winamp for both audio playback and sound effects. This DLL file is also used in several games, for the purpose of processing certain advanced sound options. The purpose of this DLL is to provide a particular function for the application, after which the application itself will access and utilise.

This file is very important for the overall stability of your computer, as its responsibilities are to the operating systems sound modules. Games that require the mss32.dll file will fail to run if this file is corrupted or missing.

Mss32.dll errors, as a general rule, typically occur when the end user attempts to run a particular program. However, in rare circumstances, it has been known to occur while the system is either shutting down or booting up.

What Causes Mss32.dll Errors?

Mss32.dll errors are caused by a number of different things, like the vast majority of DLL file errors, the mss32.dll error may tie into issues elsewhere on the system. With that said, below is a rundown of some of the many causes commonly associated with this error:

  • System settings have been damaged or corrupted.
  • The application is out of date.
  • The Windows registry has been corrupted.
  • Drivers require updating.
  • Game installation files are corrupted.
  • The mss32.dll file has been deleted or corrupted.

One of the first measures that you should take when attempting to repair this error, is to ensure that the defective software, the one responsible for the error has been installed correctly, along with any Windows settings that you think may have been altered.

How to Fix It

Fixing mss32.dll errors is possible, I’m glad to say, it just requires time and effort on your part.

Before attempting any remedies for this error, the first thing I recommend you do is verify whether or not the mss32.dll file is present on your computer. To do that, simply do the following:

1. First, boot into your computer with full administrative rights.

2. Then click on the Start button, and then type mss32.dll into the Search programs and files box. For Windows 10 users, simply type into the Search Box on the Taskbar.

start -> mss32.dll

Note: Windows XP has its own built in Search Feature which you can learn more about here.

3. If Windows is able to locate the file, Copy it.

search file -> copy mss32.dll

4. Then press windows key + R, type C:\Windows\System32 and click on OK.

run -> system32

Note: C:\Windows\System32 is the default location of the mss32.dll file, so this method will only work if the mss32.dll file is found outside of its default storage location.

5. When the System32 folder appears, right click and select Paste.

system32 folder -> paste -> mss32.dll

If you’re lucky, this may fix the problem.

Run a Registry Scan

One of the biggest contributors to errors such as “mss32.dll file is missing” or “mss32.dll not found” is the corruption of specific keys within the Windows registry. The registry is basically the central database of the operating system, used for storing configuration data for both the software on your computer and the hardware inside it. Although the registry is the most important area of the computer, it’s also a major contributor of errors.

Not many people are aware of this, but due to the design of the registry, it’s prone to causing DLL errors, a reality which is not set to change as long as DLL files exist.

Each time you use your computer, hundreds of different DLL files are loaded into the system, all with the help of the registry. When issues start to manifest inside the registry, it leads to the kinds of errors that you are experiencing right now. The end result leaves the end user needing to fix the registry in order to resolve the error. Fortunately, this can be done by using a professional registry cleaner tool like RegCure Pro.

RegCure Pro is a very powerful registry cleaner and optimisation suite, which features many useful tools and functions.

Reinstall Program

It’s not uncommon for the program or game that requires the mss32.dll file to become damaged or corrupted, resulting in the respective error. Despite the significance of the error, it’s definitely something that you can fix and in most cases a simple reinstallation of the culprit program is all that is required.

In order to do this, you must first uninstall the program, and then install a fresh copy of the application. The uninstallation is the most important phase, as you want to remove all traces of the program from your computer. Ideally you’d want to use an uninstallation tool such as Max Uninstaller, which is designed for just that:


But if you don’t, you’ll need to carry this process out manually, my post on uninstall problems elaborates further.

Update the Program

If after reinstalling the application, the problem still persists, then you may want to look into possibly updating the application. Active programs are regularly being updated with new patch releases. You can usually find these updates on the developer’s website, so I say that’s the first place you check.

Updating the application will fix a number of problems present in the code and may just fix the mss32.dll error in the process.

Copy Mss32.dll File to System

If all the solutions fail to fix the mss32.dll error, then your last option will be to place a new copy of the mss32.dll file into your System32 folder. Whether or not the mss32.dll file is present on your computer should already have been determined prior to you reaching this point; if it is present, then it’s likely that there is something innately wrong with the file. In which case, copying a working version of the file to your computer should fix your error.

To do that, simply do the following:

1. First, boot into your computer with full administrative rights.

2. Then visit the following location and download the folder to your computer:

3. Then press windows key + R, type C:\Windows\System32 and click on OK.

run -> system32

4. When the System32 folder loads up, locate the mss32.dll file and rename it to mss32BACKUP.dll – Right click and select Rename.

change mss32.dll to mss32BACKUP.dll

5. Then open the folder and extract the file to the C:\Windows\System32 folder. -> extract -> system32 folder

6. Then press windows key + R, type cmd and click on OK.

open command prompt through run command box

7. When Command Prompt loads up type regsvr32 -u mss32.dll and hit the Enter key.

run regsvr32 -u mss32.dll command to unregister file

8. Then type regsvr32 mss32.dll and press Enter.

register file with regsvr32 mss32.dll command

This whole process will effectively replace the mss32.dll file on your system with the new one, which in theory should rectify the issue. This method is very effective at fixing DLL errors.
