SOLVED: MSCOMCTL.OCX Download & Register on 64 Bit Windows

If you are working for an old application you may be presented with the error:

Component ‘MSCOMCTL.OCX’ or one if its dependencies not correctly registered: a file is missing or invalid:


In this case you have two tasks to complete and neither of them are obvious:


MSCOMCTL.OCX is part of Visual Basic 6 Package and you can download you can just download the MSCOMCTL.OCX directly from us HERE.
UPDATE – MAY 2020- Alternately you can surf to the following address but we removed the clickable link because one of our security checks has marked it as an “aggressive site” so use at your own peril:


You need to know if you are using a 32bit or 64bit version of Windows and because this is not 2002, we are assuming you want to install it on a 64bit PC.  If you try to register MSCOMCTL.OCX (which is 32 bit) on a 64 bit system and you put it in the typical C:\WINDOWS\SYSTEM32 folder you will get:


  1. dllregisterserver-in0mscomctl.ocx-succeededIf you are using 64 bit Windows copy the MSCOMCTL.OCX to C:\WINDOWS\SYSWOW64
    (If you are using 32 bit Windows copy MSCOMCTL.OCX to C:\WINDOWS\SYSTEM32)
  2. Open a CMD or PowerShell prompt (as an administrator) and change into C:\WINDOWS\SYSWOW64
  3. Type

    regsvr32 mscomctl.ocx

  4. Press ENTER
  5. Enjoy

      That is odd. You have 64bit because you are working in SYSWOW64 and I know that works… Have you rebooted? Likely a silly question and I don’t think it is required but it is a good starting point. Get back to me with errors and issues and I WILL work on it.

    Hello, thanks for the article, either I did it wrong or I need more help.
    First, when I tried to register it in Sys32, it didn’t say what you’ve said it would, it said it wasn’t compatible, and I should check and see if I have a 32 bit or 64 bit version… Then I put it in the SysWOW64, and when I tried, it gave the error you said it would give before: THE MODULE ‘MSCOMTRL.OCX’ WAS LOADED BUT THE CALL TO DLLREGISTERSERVER FAILED WITH ERROR CODE 0X8002801C So please if you could tell me what I need to do, thanks 🙂

      Dont open the CMD prompt using run. Follow the below steps.
      1) At the start menu press CMD and you will find the CMD prompt. Do not press button.
      2) Right click the CMD prompt application and select the option “Run as administrator”
      3) Now paste the below code and press enter
      regsvr32 c:\windows\sysWOW64\mscomctl.ocx
      Thats it.

    Some others have said to find an earlier version of mscomctl.ocx such as the 2015 version and load that first.

    in SysWOW64 I have copied the mscomctl.ocx and registered it but why doesn’t it work on my visual basic 6.0 application. so that one of the components that I need to make the program can’t be opened.
    I beg to help solve my problem

    Thanks to you I have installed mscomctl,ocx on my laptop. I followed the installation steps exactly as you instructed but when I open excel the controls on msdatetime picker and ms month view are not showing up in the additional control dialog box. I have been trying to locate the date time picker and month view but I am not succeeding.. No registration error.. I get the registration error when I failed to copy the file in sys32 but after I have copied the file in syswow32 and syswow64 the registration message indicates I successfully registration mscomctl.ocx

    Thanks. It worked when i started the command as Administrator. But you have to copy the mscomctl.ocx file to the folder
