Question

How to fix ntdll dll faulting module, the module ntdll.dll was loaded but the entry-point DLLUnregisterServer was not found.

Ankit Bharti 60

In previous version of windows 11 v22h2 the .exe file was working. Unfortunately, after updating it to the v24h2 the .exe file crashes automatically and it won't open.

In EventViewer, it says

Faulting module name: ntdll.dll, v 10.0.26100

And "ntdll.dll" was loaded but the entry-point DLLUnregisterServer was not found.

Also says make sure that "ntdll.dll" is a valid DLL or OCX file.

please help me solve this ASAP.

URGENT!!!

Even though the crash might occur in ntdll.dll, the problem is not typically with the dll itself, it's with the data structure or memory address that the application .exe is passing in the API call.

What can you tell us about the .exe that you are running? Is this a program that someone in your organization wrote? Do you have the source code? Is this a 3rd party product? Can you contact the developers support team to see if they have an updated version or if other users have encountered the same problem?

Hi, I am Henry and I'd like to help.

It sounds like you're dealing with a faulting module issue related to ntdll.dll after updating to Windows 11 v24H2. Since the usual SFC and DISM solutions aren't working, here are some alternative troubleshooting steps:

1. Check Compatibility Mode

Right-click the .exe file → Properties → Compatibility tab.
Enable Run this program in compatibility mode for an earlier Windows version.

2. Reinstall the Application

If the .exe worked in v22H2, try uninstalling and reinstalling the application.
Look for an updated version from the developer.

3. Verify DLL Integrity

Open Command Prompt (Admin) and run: dir C:\Windows\System32\ntdll.dll
Ensure the file exists and matches the expected version.

4. Check Event Viewer for More Details

Open Event Viewer → Windows Logs → Application.
Look for additional error messages related to the crash.

Let me know if any of these solutions work for you.
