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 error means that your graphics card or current graphics drivers, are not able to run DirectX 9. All Graphics cards from 2007 and later are supported for DirectX9. To fix this you can try to update your graphics card drivers. If that does not work you must get a DirectX9 supported Graphics card or a new computer.  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:

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!

    I’m having frequent errors with MMD where the program sometimes refuses to open at all after I restart my computer. No message, no notifications, nothing. I click on it twice, it loads, and then abruptly stops. I’ve searched for a while for this error, but it feels like nobody else has had to deal with this before. I’ve had to reinstall MMD (even using different versions) multiple times due to this. I’m not entirely sure what the deal is.

    Do you guys know anything about this?

    So, I’m aware that the laptop I use is quite slow and stuff and that MMD won’t run as fast but I have run into a problem I haven’t had before while working with MMD.

    I used to be able to render MMD videos just fine but now when I try to render any video (with the same settings I have always used), it starts to say ‘(Not Responding)’ for about 30 minutes after it records a frame and I don’t know why. I really want to render an MMD video again but it just won’t render without it stop responding. Can anybody help?

      What changed? Anything? Did you just come back from a break from MMD? Does this problem always occur, regardless of the .pmm loaded? Does it occur regardless of codec choice? Do you have space on your hard drive? Does it occur when you try to render the default Animasa Miku standing still for 15 frames? Do you have any problems running 3D accelerated games? Does it occur if you use a fresh install of MMD, without MME?

      In your shoes, those are the questions I’d be investigating in order to figure out what went wrong.

    Help! My accessory manipulation panel disappears when I load a model and I can bring it back… How do I fix this?

    • April 8, 2019    

      There are two “modes” – model mode, when you select a particular model to configure its bones, and camera mode, when you set up the camera, can see the screen exactly as it will be rendered to picture/video, and this is where you can configure accessories as well. Press the button “Model/Camera” in the lower left corner of the render screen, and your accessory panel will be back.
