Troubleshooting MMD errors and setting up

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)

winvista-8-1_control_panel_smallClick image for full size

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:
Getting started
Make a music video
Render your video in HD 60fps (Little bit more advanced)
Keep the faith MMD
Upload your video to YouTube

That`s about it, for this article!

If you get a different error or if it still won’t work, please let me know by posting a comment below or on my YouTube video.

UPDATE 06-05-2016:

Rivised the DirectX part of the post and added Locale part

    Olá, eu já comecei a usar o MMD faz uns 2 dias, eu já sabia usar ele, mas ele está com um problema que eu não consigo resolver, quando eu tento salvar o vídeo e escolho o programa pra reproduzir e depois enviar pro YouTube, mas quando eu escolho esse programa tipo o “UT Video RGB VCM” fala que o “MikuMikuDance.exe parou de funcionar” e é a mesma coisa com outros, o que eu faço??

    • July 21, 2017    

      What other codecs did you try? try to install Cinepak or ffdshow and see if they work better. Also make sure you have DirectX 9.0c and MS Visual C++ Redistributable libraries that are listed in this article.

    Hello I’m having this problem with MME. I never had this problem tho. So I was rendering my animation then MMD stopped and than said “failed to reset MME” I dont know what is it mean because I never had this problem before is just random.
    Oh and btw I’m using tons of effects some are heavy than others.

    • July 21, 2017    

      And have you tried again? Does it always happen? Does it always happen in the same frame of the render?

    I downloaded the DirectX and everything was fine, but this message popped up:
    An internal system error occurred.
    Please refer to DXError.log and DirectX.log in your Windows folder to determine problem.
    I don’t know what this means or what to do..

    • June 23, 2017    

      For starters, try to install once again. If it proves to be *not* a fluke, then try to find those files (they’ll normally be in C:\Windows) and see what they say. DirectX.log will be quite long, the actual sign of disorder should probably be found closer to the end.

        I got it working, and I tried working MMD but it never works… I got DirectX working and I changed my region… I extracted MMD like it says, but then this pops up:
        The application has failed to start to start because its side-by-side configuration is incorrect. Please see the application event log or use command-line sxstrace.exe tool for more detail.
        I don’t know if I’m missing something or my computer wont allow MMD to work

        • June 25, 2017    

          The side-by-side problem is actually described in this very article, and it’s quite solvable.

    Heya, I had an issue with the missing DLL file and followed your instructions, however it still showed the same error message. I use a computer with Windows 10.

    • Reggie_Dentmore Reggie_Dentmore
      June 9, 2017    

      “… followed your instructions” which were what? The missing DLL error is generally caused by the need to install the appropriate DirectX Runtime update. Did you install that update? … if you DID and you still get the error message, what, exactly does your error message say?

    I made a motion the other day and when I load it onto the model is says “This is not a Vocaloid Motion Data File” Does anyone know how to fix this? btw it is a .vmd file. I NEVER HAD THIS ERROR BEFORE!!!! CAN SOMEONE PLZ HELP ME!!!!!!!!!!!!!

    • April 17, 2017    

      By saving the motion, do you mean saving the whole project with File->Save that produces a pair of .pmm/.emm files, or saving individual model’s motion with File->Save Motion Data, which produces a .vmd file? Loading those takes separate commands accordingly.

      • Kiara Kiara
        April 18, 2017    

        Savig an individual model motion.

        Or do you know how to fix the “This isn’t for Polygon movie Maker” when you load a while Project?

      • Kiara Kiara
        April 18, 2017    

        But the error happens when I load the motion onto a model (File->load motion data).

        • April 18, 2017    

          So the file you try to load onto a model is a .vmd?

          • Kiara Kiara
            April 18, 2017    

            Yes, it is a .vmd file

            • April 18, 2017    

              All right, you have a .vmd file. Load a model, make sure that you’re in model mode and not screen mode (model’s bones should be visible) and select File->Load Motion Data. It should work OK; if not, upload the .vmd file somewhere and post a link.

  7. April 2, 2017    

    I had to reboot my pc because of a certain problem, mmd used to work before, but now it’s just saying “the program can’t start because d3dx9_43.dll is missing from your computer.” I downloaded the things for the side by side error, followed your step, and it’s STILL not working.

    • April 2, 2017    

      oh nvm, haha, i just had to run the setup loooool.

    I keep getting this error ;-; but it was working fine yesterday but now its not at all. what do i do?
    Cannot execute Rar$EXa0.189\MikuMikuDanceE_v926\MikuMikuDance.exe”

    • March 31, 2017    

      What was working “fine” yesterday was RAR archive’s *temporary* unpack folder. That’s not the proper way to work with programs, and I’m amazed that you got it working at all in the first place. *Unpack* the archive into a real folder in your HDD and work from that one. There are several archivator programs that can proceed it, but for MMD-related reasons, Bandizip is most preferable.

    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.

    • March 21, 2017    

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

  10. March 19, 2017    

    I did everything that the video said and there’s a third problem, it is the Winrar and after I extract it to “games” and open MMD, it go back to problem one, side-by-side and dll problem! why are there so many problem’s? I download this 5 times

    • March 19, 2017    

      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.

      • Buster Buster
        March 9, 2017    

        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.

            March 10, 2017    

            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.
