A feature article by Learnmmd's parkeerwacht!How do I fix MMD errors? How do I fix the side-by-side error? How do I fix the missing DLL error? How do I setup MikuMikuDance? How do I solve MMD problems? How do I install MME effects?

Hey LearnMMD readers, it`s parkeerwacht with another tutorial. This time it is a very basic one! How do you solve common issues with MMD. I am writing this article, because I have seen alot of readers saying they run into these problems. The solution is actually allready on the site. In multiple articles! Even on the download page itself! I assume most people read over them soo, I want to create this article to solve them once and for all! (hopefully)

How to solve common MMD problems, and set up MMD so you can start animating!

To start off I suggest you watch my video on the topic:

In this video I will explain everything inside this article.

Downloading MMD

You can get MMD from the downloads page or from the VPVP page (1.3 for 32-bit MMD and 1.4 for 64-bit MMD)

To download the proper version of MMD you can check if your system is 32-bit or 64-bit. (32-bit MMD will run on 64-bit machines) To look this up go to system in the control panel of Windows: (Select Large Icons in the dropdown in the top right for windows Vista-8.1 and select classic view in Windows XP)

In windows 10 you can go to settings > System > About:


Click Image for full size

Depending on your windows version the screen you will see differs, look for something that says: 64-bit operating system or X64 edition for Windows XP. on the image above you can see how it looks for 64-bit Windows 10, but all systems should have something like that.

This is how it looks for my test system: (a Virtual Machine running on my computer)


In Windows XP it doesn`t say 32-bit so if it doesn`t say X64 Edition it`s 32-bit. (I found this image online)

My test system is 32-bit so I download the 32-bit version. If it says 64-bit download the 64-bit version MMD. You can also use 32-bit MMD on these systems as well, but I prefer 64-bit MMD.

The Side-by-Side configuration error.

Common question by our readers:

I downloaded MMD but it gives me the following error: “The side-by-side configuration is incorrect” How do I fix this?

On my Windows XP test system it showed up as the following:

Config-error-XPThis is the same as the Side-by-Side configuration error.

This means you do not have the C++ Libraries installed!

To fix this error:

Download the following packages for 32-bit MMD:

for 64-bit MMD, install the following packages:

You will need to have full administrator access to the computer in order to install them.

If you still get the error after installing, reboot your computer.

The missing DLL error

Common question by our readers:

My MMD crashes on startup with the error:”This application has failed to start because D3DX9_**.DLL was not found.” Can you help me?  (Different DLL`s may be shown usually D3DX9_32.DLL or D3DX9_43.DLL. I have noted different DLL`s)

For me it showed up like this:


To fix this error:

Install the following package:

DirectX 9.0c End-User Runtime

Make sure to restart the computer if it doesn`t work immediately!

If you keep getting the error after installation, or when you get an error when you try to install. Use the following setup:

Download and install the following package:

DirectX End-User Runtimes (June 2010)

To install it create a new folder on the C drive named TMP. Let it extract to that folder.
Now open the folder and run: DXSETUP.EXE
This will install DirectX on your system.

If you get the following error after installing DirectX:


This means that your system is incabable of running DirectX9. To fix this is to get a DirectX9 supported Graphics card or a new computer. All Graphics cards from 2007 and later are supported for DirectX9. This error can also mean that the current video mode doesn`t support DirectX9. Since I am on a Virtual Machine I get this error as well.

Japanese Locale

For some features of MMD to work properly, and prevent scrabled filenamed when extracting MMD data, you must set your system locale for non-unicode applications to japanese.

To do this: go to the controll panel. (For windows 8.1 and 10 users: right click on the start button and click on controll panel) Then click on Region, under the administrative tab click on change system locale, select Japanese from that list. Click on OK and reboot the computer.

MME effects

Once you have got MMD running, you should install MME. This plugin gives you the ability to use different effects in your videos!

Download MME at our downloads page, make sure to download the corrosponding version of MME to your MMD version (64-bit MME for 64-bit MMD, and 32-bit MME for 32-bit MMD)

open the archive and copy these files to the same folder where MikuMikuDance.exe is located:


DO NOT PUT THEM IN THE DATA FOLDER! I have seen people do this. This won`t work!

If it worked it should show up in the top right corner of the MMD interface:


Soo, I got it all working. What should I do next?

Well that’s for you to decide I have collected some links that will help you get started:

That`s about it, for this article!

    I still get the side by side error. I have the CC thingy installed but it still won’t work. I’ve reinstalled it lots of times and rebooted my device but it still showing the same sign.

      Open Control Panel’s Programs and Features window and see what Microsoft Visual C++ Redistributable versions are listed there.

      Open Control Panel’s Programs and Features window and see what Microsoft Visual C++ Redistributable versions are listed there.

    I try to load MMD however the program doesn’t run at all.
    It doesn’t show any kind of error message.

    How I can fix it?

    • March 8, 2017    

      Do you have a Windows desktop computer? (the question may look silly, but we had confused visitors from both Apple and Chromebook fields)

      Make sure you have DirectX 9.0c and Visual C++ Redistributable libraries installed, as described above.

        It always worked, however after some time upon double click it had the load icon working for a while, however it didn’t loaded at all.
        It doesn’t show any kind of error message and neither appears in the task manager at all.
        That issue happened first in the 32 bit and now started in the 64 bit version as well.

          I’m not as tech-savvy as the other teammates so I can’t really pinpoint the technical issue, but here’s a solution I do know that works.

          – Download a fresh MMD copy (make sure it’s the same version as your old one)
          – Extract it to your desktop.
          – Copy the “Data” folder from it.
          – Open up your old MMD folder
          – Delete the old Data folder and replace it with the new one.
          – Try running MMD now.
          Let me know if this works.

            I redownloaded and saved in a diferent folder.
            This time it worked just fine and I transfered the models there.

            I’ll keep that in mind if it happens again.

        • March 10, 2017    

          I’d modify the advice above like this:

          – Download a fresh MMD copy.
          – Extract it to an empty folder.
          – Launch it and see if it works.
          – The next step will depend on the results.

          But yes, you should try that.

          What ever did happen at your computer between the time it worked and now?

            For my case, nothing particular happened. It just STOPPED working all of a sudden.

            I’ve encountered this problem several times. At first MMD works fine, then two or three months later it won’t open. Used the method above. Works normally for two or three times before it refuses to open again. I kept swapping the data folder every time it happens, and after 2 or 3 more swaps it finally decided to stay open, but a few months later the symptoms came back. Weird.

            Oh, and my laptop is clean so I doubt it’s actually a virus.

            And, the reason I only swapped the data folder is because I kept all my models and projects in my original MMD folder. Saved some hassle of moving those 10 GB folders back and forth. I kept a fresh data folder on my desktop just in case the symptoms reappeared, so I can just copy it to the main folder quickly.
