The RunDLL error “There was a problem starting. The specified module could not be found” occurs mostly when Windows users try to open a hard drive or an external drive. However, some users get the error only when they try to open a shortcut pointing to an executable file stored on that drive.

Rundll.exe files are system processes that are directly related to your Windows operating system. Rundll and later versions, called Rundll 32, are part of a vast network of code and data shared by many programs on your computer. They help your operating system achieve speed and memory efficiency by reusing the same code or files while performing many different program functions.

What causes a Rundll error?


  1. Incorrect deletion of a DLL file.
  2. Missing DLL errors are caused by deleting a generic DLL file when uninstalling an application.
  3. Shared DLL file deleted or infected by a virus or Trojan horse.
  4. Incorrect or wrong DLL entries in the Windows registry.
