What are mmx64.efi Error Messages?


mmx64.efi Runtime Errors

Runtime errors are Wubi errors that occur during "runtime". Runtime is pretty self-explanatory; it means that these EFI errors are triggered when mmx64.efi is attempted to be loaded either when Wubi is starting up, or in some cases already running. Runtime errors are the most common form of EFI error you will encounter using Wubi.

In most cases, mmx64.efi runtime errors occurring while the program is running will result in the program terminating abnormally. Most of these mmx64.efi error messages mean that Wubi was either unable to locate this file on startup, or the file is corrupt, resulting in a prematurely-aborted startup process. Generally, Wubi will be unable to start without resolving these errors.

Some of the most common mmx64.efi errors include:

  • mmx64.efi - Bad Image.
  • mmx64.efi Application Error.
  • mmx64.efi could not be found.

System Error


The program can’t start because mmx64.efi 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 mmx64.efi error is key to properly resolving these errors. Although most of these EFI errors affecting mmx64.efi will happen during startup, occasionally you will encounter a runtime error while using Wubi 12.04. This can occur due to poor programming on behalf of Wubi, conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware. Also, these types of mmx64.efi 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 mmx64.efi problems.

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



Download mmx64.efi Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying mmx64.efi to your appropriate Windows system directory. Wubi typically does not release Wubi EFI 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 mmx64.efi and all other EFI files for Wubi. An incorrectly installed EFI file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
