Errors like “Msxml4.dll not found” or “Msxml4.dll is missing” are typically caused by malicious software or viruses corrupting your computer’s registry; this article will show you how to identify and remove these threats.

What are Msxml4.dll Not Found or Missing errors?

When Windows cannot locate the Msxml4.dll file, you will see an error message that reads “Msxml4.dll Not Found” or “Missing.” Numerous Windows applications rely on Microsoft’s XML Parser, of which this file is an integral part. When Windows cannot open a file because it is corrupted or missing, an error message is displayed.

This error might happen for a number of different reasons. When the registry is corrupted or broken, it is usually the culprit. The computer’s settings and configurations are kept in a database called the registry. Faults like the “Msxml4.dll not found” message appear when it has grown cluttered with errors and broken settings.

An infection by a virus or other malicious software is another common reason for this message. Threats like these might corrupt or remove essential system files like Msxml4.dll. You should check your computer with antivirus software if you find any signs of infection so that you can eliminate the danger and fix any harm.

Last but not least, the Msxml4.dll file itself may be corrupted or missing, leading to this error message. If this issue appears after installing Windows Update, it’s possible that some of the upgraded files became corrupted. If the problem persists after updating the XML Parser, try downloading it from Microsoft’s website and installing it again.

How to Fix Msxml4.dll Not Found or Missing Errors?

There are a few solutions you can try if you’re getting “Msxml4.dll not found or missing” issues.

You should verify first if the file is truly missing before attempting to replace it. Just use Windows Explorer’s search function to track down the document. If the file is not already on your computer, you will need to get it from somewhere online and save it in its proper directory.

Following the file’s download, Windows registration is required. The command “regsvr32 msxml4.dll” can be entered into the Command Prompt to accomplish this. Just hit Enter and hang tight while everything finishes up.

Try restarting your machine to see if it solves the problem.

Virus Scans and Malware 

  1. Malware Scans and Checks

If you’re seeing a “Msxml.dll was not found or is missing” message, your first line of defence should be to remove any malware that might be present on your computer. These kinds of issues are frequently brought on by malware, which may be detected and removed with a scan.

There are a few options for scanning for malware, but we advise utilising an established anti-malware tool like Malwarebytes. Launch a scan with Malwarebytes after you’ve installed it to check for malware.

If Malwarebytes turns up clean, you can always resort to Windows Defender. To access Windows Defender, type “Windows Defender” into the Start menu’s search bar. To begin a scan, select the “Scan now” option.

If you want to be sure that no malware is left behind once the scan is finished, you should double-check for any leftovers.

Manual Removal of Msxml4.dll Not Found or Missing Errors

Several solutions exist for resolving Msxml4.dll Not Found or Missing Errors. You might try uninstalling Msxml4.dll from your computer and then installing it again to fix the problem.

Here’s what you should do:

To begin, choose a reliable online source and obtain the Msxml4.dll file.

  • Navigate to the “C: WindowsSystem32” folder and locate the Msxml4.dll file currently installed on your computer.
  • Simply renaming the existing Msxml4.dll to Msxml4 old.dll will solve the problem.
  • The new Msxml4.dll file you downloaded should now be pasted into the “C:WindowsSystem32” folder.
  • After making any necessary modifications, restart your computer to determine if the errors persist.


Incorrect registration of the MSXML 4.0 component or damaged system files are common causes of MSXML4.dll issues. One solution to these problems is to use a Registry cleanup programme to search for and replace any invalid or missing registry entries. The DLL file may be corrupted, in which case you can try manually registering it or reinstalling MSXML 4.0. In the event that these solutions don’t work, you may need to download a new copy of MSXML4.dll from a reliable source and install it on your computer.
