Turn off Antivirus to Fix “RegSvr32 Failed with Exit Code 0x3” Error
To fix the “RegSvr32 Failed with Exit Code 0x3” error when unable to register a DLL/OCX file in Windows 10, try turning off your antivirus temporarily. Antivirus software can sometimes block the registration process, so disabling it can help.
Open your antivirus software and locate the option to temporarily disable it. Once disabled, try registering the DLL/OCX file again using the “regsvr32” command in the Command Prompt.
If turning off your antivirus doesn’t work, there may be a permissions issue. Make sure you have administrative privileges and try running the Command Prompt as an administrator. Additionally, ensure that the DLL/OCX file is in the correct location and that it’s the correct version for your Windows operating system (32-bit or 64-bit).
If you’re still having trouble, try running a security check on your system and see if there are any software conflicts. You can also try reinstalling the software that uses the DLL/OCX file, or searching for an updated version of the file online.

This code checks if the specified DLL or OCX file exists, and if so, attempts to register it using regsvr32 with the /s switch to run silently. If the file is successfully registered, a message box is displayed indicating success. If the file is not found, a message box is displayed indicating failure. This is just a basic example, and may need to be modified or customized depending on the specific needs of the user or application.
User Solutions to Resolve “Unable to Register the DLL/OCX” Error
To resolve the “Unable to Register the DLL/OCX” error in Windows 10, users can try several solutions. First, ensure that the DLL or OCX file is compatible with your system’s architecture (32-bit or 64-bit). If it is, try running the installation as an administrator.
If that doesn’t work, try registering the DLL or OCX manually using the regsvr32.exe command in Command Prompt. Make sure you enter the correct file path and name. If you receive an error message that says “dllregisterserver failed” or “the module failed to load,” it may be due to a dependency issue.
In that case, use the dependency walker tool to identify missing dependencies. Additionally, some third-party software may be causing the error. Try uninstalling programs like Jackaudio, ClaimMaster, or Cakewalk. Finally, check for any corrupt system files using the sfc /scannow command, or try a Windows search for missing DLLs like mscomctl.ocx, winscp, isdone.dll, or dragext64.dll.
