What are MpSigStub.exe Error Messages?


MpSigStub.exe Runtime Errors

Runtime errors are CyberLink Media Suite errors that occur during "runtime". Runtime is pretty self-explanatory; it means that these EXE errors are triggered when MpSigStub.exe is attempted to be loaded either when CyberLink Media Suite is starting up, or in some cases already running. Runtime errors are the most common form of EXE error you will encounter using CyberLink Media Suite.

In most cases, MpSigStub.exe runtime errors occurring while the program is running will result in the program terminating abnormally. Most of these MpSigStub.exe error messages mean that CyberLink Media Suite was either unable to locate this file on startup, or the file is corrupt, resulting in a prematurely-aborted startup process. Generally, CyberLink Media Suite will be unable to start without resolving these errors.

Some of the most common MpSigStub.exe errors include:

  • MpSigStub.exe - Bad Image.
  • MpSigStub.exe Application Error.
  • MpSigStub.exe could not be found.
  • MpSigStub.exe could not be installed.
  • MpSigStub.exe could not be launched. Class not registered.
  • MpSigStub.exe could not be started.
  • MpSigStub.exe failed to initialize properly.
  • MpSigStub.exe has encountered a problem and needs to close. We are sorry for the inconvenience.
  • MpSigStub.exe is not a valid Win32 application.
  • MpSigStub.exe is not running.

  • Error starting program: MpSigStub.exe.
  • Faulting Application Path: MpSigStub.exe.
  • The file MpSigStub.exe is missing or corrupt.

System Error


The program can’t start because MpSigStub.exe is missing from your computer. Try reinstalling the program to fix this problem.

Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

Finding the source of the MpSigStub.exe error is key to properly resolving these errors. Although most of these EXE errors affecting MpSigStub.exe will happen during startup, occasionally you will encounter a runtime error while using Microsoft Malware Protection. This can occur due to poor programming on behalf of Microsoft Corporation, conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware. Also, these types of MpSigStub.exe errors can occur if it has been accidentally moved, deleted, or corrupted by a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
