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.
mmx64.efi could not be installed.
mmx64.efi could not be launched. Class not registered.
mmx64.efi could not be started.
mmx64.efi failed to initialize properly.
mmx64.efi has encountered a problem and needs to close. We are sorry for the inconvenience.
mmx64.efi is not a valid Win32 application.
mmx64.efi is not running.
Cannot find mmx64.efi.
Error starting program: mmx64.efi.
Faulting Application Path: mmx64.efi.
The file mmx64.efi is missing or corrupt.
Windows failed to start - mmx64.efi.

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to poor programming on behalf of Wubi, conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware.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.

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your mmx64.efi issue. These troubleshooting steps are listed in the recommended order of execution.

Please enter the administrator password (if applicable / prompted).
Follow the steps in the System Restore Wizard to choose a relevant restore point.

Step 3: Perform a Windows Update.

If Those Steps Fail: Download and Replace Your mmx64.efi File (Caution: Advanced)

If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate mmx64.efi file version. We maintain a comprehensive database of 100% malware-free mmx64.efi files for every applicable version of Wubi. Please follow the steps below to download and properly replace you file:

Locate your Windows operating system version in the list of below "Download mmx64.efi Files".
Click the appropriate "Download Now" button and download your Windows file version.
Copy this file to the appropriate Wubi folder location:

Windows 10: C:\ubuntu\winboot\EFI\

To avoid data loss, you must be sure that you have backed-up all of your important documents, pictures, software installers, and other personal data before beginning the process. 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.
