What are MsMpEng.exe Error Messages?


MsMpEng.exe Runtime Errors

Runtime errors are Microsoft Office Access 2010 errors that occur during "runtime". Runtime is pretty self-explanatory; it means that these EXE errors are triggered when MsMpEng.exe is attempted to be loaded either when Microsoft Office Access 2010 is starting up, or in some cases already running. Runtime errors are the most common form of EXE error you will encounter using Microsoft Office Access 2010.

In most cases, MsMpEng.exe runtime errors occurring while the program is running will result in the program terminating abnormally. Most of these MsMpEng.exe error messages mean that Microsoft Office Access 2010 was either unable to locate this file on startup, or the file is corrupt, resulting in a prematurely-aborted startup process. Generally, Microsoft Office Access 2010 will be unable to start without resolving these errors.

Some of the most common MsMpEng.exe errors include:

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

System Error


The program can’t start because MsMpEng.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 MsMpEng.exe error is key to properly resolving these errors. Although most of these EXE errors affecting MsMpEng.exe will happen during startup, occasionally you will encounter a runtime error while using Microsoft® Windows® Operating System. 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on behalf of Microsoft Corporation, conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware.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 MsMpEng.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.

GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve MsMpEng.exe problems.

If you are not currently backing up your data, you need to do so immediately.



Download MsMpEng.exe Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying MsMpEng.exe to your appropriate Windows system directory. Microsoft typically does not release Microsoft Office Access 2010 EXE files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing MsMpEng.exe and all other EXE files for Microsoft Office Access 2010. An incorrectly installed EXE file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
