Help! Cryptic error related to MCI32.OCX in Windows XP

by sparky_melon / May 16, 2010 8:42 AM PDT

Hi i am new to this. I really dont know much about programming. I am using Windows XP latest service pack.

I tried to open a MIDI music software, and suddenly i got a pop up window telling me this message:

Failed to load control 'MMControl' from MCI32.OCX. Your version of MCI32.OCX may be outdated. Make sure you are using the version of the control that was provided with your application.

I dont know what to do to solve this problem. As far i did some research on my windows files i have the following version of MCI32.OCX ( is there any newer ? If so where to download it?

I tried to install the latest Visual Basic 6.0 Runtime files from with no luck. I still have the same problem.

Is there anyone out there who can help me? Sad

I can't find the title of this software in your post. Often the solution is to uninstall that App and reinstall it.

Still no luck

The software is a stand alone application that doesn't require installing procedure. As i told in the original post, i did updated the VB 6.0 runtime libraries and nothing happened.
What else i can do?

And all the VB apps I used had an installer (tipping my hand I author VB6 apps back when) the fix is still to be tried.

But again no title so I'm left to leave you alone to sort this out. Not that some think it matters but like a car you want to know what make, model, and more details to work the problem. Some folk want to keep details to themselves and if I ask and they don't tell, I apologize and unsubscribe.

So there it is. I apologize and will unsubscribe.

My parting advice is to ask the App's author for help.

How about this?

The application is called Midi Convert (ver.1.0) and the author seems Rosetta, the application itself doesnt give more details than that.

I found it on this website:

on GET CODE option Zip file, includes .BAS files for PICBASIC Proton software to be used in Microcontrollers.

As i said, it is a small application 120 kb and it is a stand alone one, it doesnt require installation procedure, you just double click it, and it is supposed to open it automatically.

In the article,
seen here, it does explain a procedure related with that file MIDI CONVERT.EXE, and it tells that the program was written in VIsual Basic 6 and the purpose of that program is to convert a MIDI file into a series of LDATA statements. The author of this software (2003 / and probably not supported now), does say the user may need VB6 runtime libraries for the program to operate. However i did managed to download VB6 runtime libraries and still didn't solved the problem, as stated earlier.

I am sorry if my english is not very good, because is not my mother language, but please do not underestimate my knowledge on trying to solve this issue. However due to the nature of this problem i need help. and as a result i am not trying to hide any information.

I hope details given can give clues to anyone interested solving my problem Sad

I received your PM and, unfortunately, your odds of running the program are not good. However, I will note that:

1.) You can download mci32.ocx (version 6.00.8418) by clicking here.
2.) I believe the file should be located in C:\Windows\System32 but is not present in a default Windows XP installation.
3.) The program may actually be looking for an older version of the file, not a newer one, complicating the issue.

You can try to get it working, but you'd be better off selecting an alternative that 'just works' and is still supported/actively developed.

Best of luck.

Thank you for your kind response to my problem.

Once i applied the update to MCI32.OCX file to the current version, i was able to open the program and it worked fine.

File location
by sparky_melon / May 20, 2010 11:36 PM PDT

Yes it was located in C:\Windows\System32 , i just replaced the older file with the new one and that solved the problem.
