Common issues With newdev.dll

Fix Newdev.dll Error

Overview - What is newdev.dll?

Newdev.dll is a standard WinOS library involved in the process of adding new hardware to your computer. It's a file that is needed by WinOS to work correctly, and therefore shouldn't be moved or deleted.

Every time you add a new piece of hardware to your system, the "Add a New Device" wizard is evoked. The newdev.dll file is part of that system, and as new hardware devices are detected automatically, the newdev.dll system process is active all the time.

Common Errors When There's an issue With newdev.dll

Even though newdev.dll is primarily for installing and adding new hardware devices, it's also regularly called by a variety of WinOS and third-party applications. If newdev.dll is missing or corrupt you may start seeing error messages such as this:
  • "Cannot find newdev.dll"
  • "Cannot start application, a required component is missing: newdev.dll"
  • "The file newdev.dll is missing"
  • "This application failed to start because newdev.dll was not found. Reinstalling the application may fix this problem"

Depending on which application is trying to call newdev.dll depends on when you see the error messages. For example, you may see this error on start-up if an application that requires newdev.dll is in your start-up folder, or is called from the registry during start-up. You may also see one of these messages when you start particular applications.

A missing or corrupt newdev.dll file will not cause any significant issues, although because many system processes call newdev.dll you will probably receive many error messages while working on your computer, which can be disruptive and annoying. You may also experience difficulty when adding new devices to your system, and they may not automatically be installed or detected.
