Step-by-Step Guide to Fix the Error

Here’s a comprehensive guide to fix the regsvr32 mscomctl.ocx failed to load error.

Step 1: Verify the mscomctl.ocx File

First, ensure that the mscomctl.ocx file is present on your system.

1. Open File Explorer.

3. Look for the mscomctl.ocx file.

If the file is missing, you will need to download it from a reliable source. Important Note: Always ensure that the files you download come from reputable sources to avoid malware risks.

Step 2: Register mscomctl.ocx

Once you've confirmed that the file is present, the next step is to register it:

1. Open Command Prompt as Administrator:

   • Click on the Start menu, type cmd, right-click on Command Prompt, and select Run as administrator.

If you receive the error mscomctl.ocx was loaded but the DllRegisterServer entry point was not found, it may indicate that the file is either corrupted or not compatible with your version of Windows.

Step 3: Use the Correct Version of mscomctl.ocx
