Failed to load DLL file on Windows computer

On Windows startup if your system cannot or is unable to load a required dll file and you see a message – Failed to load DLL, then this post will help you. The error message could be:

  • The dynamic library dll failed to load.
  • Failed to load dll library.

failed to load dll

This error can occur if Windows OS fails to locate the DLL library which the system needs to access during startup. It could also occur if could happen if the DLL is not in a directory specified in the path or if the DLL has gone missing or corrupted. This error is commonly seen if you have removed a malware infection – but a DLL file has been left behind.

Failed to load DLL file

If you face this error, here are a few things you could try:

1] Reinstall the program

Reinstall the program which is throwing this error. Better still, uninstall it, download the latest setup file and install it.

2] Check startup programs

Check the Startup programs – especially the Windows Registry startup paths and remove the startup entry to this dll file

3] Run Registry Cleaner

Run CCleaner or any other good Registry Cleaner to clean up the residual registry and file junk

4] Re-register the DLL file

If the file in question is a legitimate DLL file that is required by one of your programs, you could try and re-register this DLL file. The Regsvr32 tool is a command-line utility that can be used for registering, and un-registering OLE controls as DLL and ActiveX (OCX) controls in the Windows operating system. If you find that some of your Windows functions are not working properly, you may need to register your dll files.

5] Use Dependency Walker

Use freeware Dependency Walker to troubleshoot, if a specific program of yours is not loading, or a service is failing to start with an error pointing to a specific dll. You can load that program or dll in Dependency Walker, to see which file is failing to load or what module is causing the problem – and then fix it.

6] Check details in Event Viewer

If nothing helps, you may need to open the Event Viewer and check for error messages or codes caused for this file.

Hope something helps!
