Thanks for your help. I got the 64 bit version and it has the MME tab but now it doesn’t load MMD., saying it failed to load the files. I don’t know what is wrong because a have a lenova yoga laptop that should have a good video card.

I also have a new problem. MMD won’t render anything over 6000 frames, do you know why.

Plz help

Can you run that by me again… … You got the 64-bit version of MMD … and it has the MME in the upper right corner… and now… ?? … MMD will not load… it DID load… and now it will not? … what error message do you get?… the wording of that message.

I have 64bit MMD.  I got the 64 bit version of MME v037 as you suggested. When I load MMD up, enough of it loads so that I can see the MMEffect tab, but then an error box for MME pops up saying, and I quote, “Initialize Error: failed to load default effect file. Please check video card capability”.  I don’t know what is wrong because I have a really modern laptop so there shouldn’t be a problem with my video card as far as I know.

Sorry if you didn’t get everything. I quickly put everything down because I have only been using MMD for 4 weeks and was really disappointed when MME didn’t work.

Thanks for all your help so far! :3

Okay… I haven’t seen that particular error before… Maybe try the regular 32-bit MME?? … or a combo of the 32-bit MMD and 32-bit MME?? I don’t think you HAVE to run 64-bit MMD on your 64-bit computer.

That latest version of MME, v037, was released so as to be compatible with the latest version of MMD …MMD 9.32 and MMD 9.32×64 … so I know that MME v037 Does work.

Let me know what happens… I can ask others of our writers if you still have issues.

Glad to help!

When I first got MMD, I got the 32 bit version and it wouldn’t run because of a dll issue that I couldn’t fix even with a dll fixer. I’ve tried running the 32 bit MME with my 64 bit MMD and the same problem has occurred. The MMEffect tab appers but MMD won’t load properly. I don’t know if my video card has actually got a problem but at the moment I think it might have since the same error message with both 32 and 64 bit MME.

Please ask some of you other writers if it’s ok with them. I don’t want to force you guys to help me.

Thanks again. You’ve been really helpful so far.

A DLL fixer… … Have you tried downloading our old DirectX 9c update… from the Downloads page? … there are old DLL files in there that MMD “needs”. … If you download and install our old DirectX update, your system may remind you that you already have a newer version of DirectX installed… Continue? … “Yes”… go ahead and add this older version…then try your MMD/MME again.

Lemme know what happens.

It worked!

It worked! And MME also now works without causing it to crash!

Thanks for all your help!!!!!!! :3

I just love success!

Don’t use a “DLL Fixer” or try to download single DLLs…

Doing a Google search for particular missing DLLS will not solve your problem. DirectX is a “system” that requires a network of interrelated DLL files… if you are missing one, you are probably missing a handful of them. The web is full of scams offering to fix your DLL error in exchange for your looking at all of their ads… don’t fall for it.

MikuMikuDance requires some of the original DLL files found in old DirectX 9c…

Newer machines come with newer versions of DirectX which may not include the MMD-required “old” DLLs. Downloading and installing the DirectX 9c update offered from the Downloads page may well be the solution to MANY of your MMD running and setup problems.

As mentioned, above… when you try to install the old DirectX 9c, your computer may pop-up a warning that you already HAVE a newer version of DirectX installed. Click “OK to Continue”, or whatever is the correct response, to go ahead and install this older version of DirectX.

Enjoy MikuMikuDance!
