Fail to load library: urlmon.dll how do I fix this?

Hi, DanieltheDino

Welcome to the Microsoft community.

Based on your description, it seems that you have encountered an issue with a Dynamic Link Library (DLL) file named “urlmon.dll” that cannot be loaded in your computer's operating system.

You should know that “urlmon.dll” is part of the Windows operating system and belongs to the ActiveX Component Object Model (COM), which is used to manage URL encapsulation and Internet protocol implementation. When you encounter “Fail to load library: urlmon.dll” error, it usually means that your operating system is having problems trying to load this DLL file. This can be due to a corrupt file, registry error, missing or corrupted system files, and so on. Solving this problem usually requires a system repair, re-registering the DLL file, updating or replacing the corrupted file, etc.

However, you mentioned that you have already tried the command to re-register the DLL file but the problem still persists, so it should be caused by a system issue. In this case, you can try the method of overlaying the installation of the system by referring to the following steps:

By this method of overriding the installation, you can clean up the current system which will help to solve some of the problems under the system.
