When you are running an old application on Windows 10, and you get an error message “Component ‘MSCOMCTL.OCX' or one if its dependencies not correctly registered: a file is missing or invalid”, it's means you need to install MSCOMCTL.OCX on your Windows 10 PC/Laptop. You can fix this issue by following solutions below.

How To Install MSCOMCTL.OCX

STEP 1. Download MSCOMCTL.OCX from Microsoft official site.

STEP 2. Extract file VisualBasic6-KB896559-v1-ENU.exe and find file MSCOMCTL.OCX

NOTE: Before you install MSCOMCTL.OCX file, you need to know your Windows 10 OS version is 32 or 64 bits. And for this article we use OS with 64 bits version. Read the article carefully, if you are on 32 bits version.

If your Windows 10 is 64 bits:
COPY file MSCOMCTL.OCX to C:\WINDOWS\SYSWOW64

If your Windows 10 is 32 bits:
COPY file MSCOMCTL.OCX to C:\WINDOWS\SYSTEM32

WARNING: If you are installing MSCOMCTL.OCX on wrong path you may see a message like this:
THE MODULE ‘MSCOMTRL.OCX’ WAS LOADED BUT THE CALL TO DLLREGISTERSERVER FAILED WITH ERROR CODE 0X8002801C

STEP 3. Open PowerShell or CMD and Run As Administrator (Admin). On this article we install MSCOMCTL.OCX on Windows 10 64 bits, so if your current CMD or PowerShell directory path is C:\WINDOWS\SYSTEM32 (32 bits), change the path to C:\WINDOWS\SYSWOW64
