What are ms64.efi Error Messages?


ms64.efi Runtime Errors

Runtime errors are AOMEI Backupper errors that occur during "runtime". Runtime is pretty self-explanatory; it means that these EFI errors are triggered when ms64.efi is attempted to be loaded either when AOMEI Backupper is starting up, or in some cases already running. Runtime errors are the most common form of EFI error you will encounter using AOMEI Backupper.

In most cases, ms64.efi runtime errors occurring while the program is running will result in the program terminating abnormally. Most of these ms64.efi error messages mean that AOMEI Backupper was either unable to locate this file on startup, or the file is corrupt, resulting in a prematurely-aborted startup process. Generally, AOMEI Backupper will be unable to start without resolving these errors.

Some of the most common ms64.efi errors include:

  • ms64.efi - Bad Image.
  • ms64.efi Application Error.
  • ms64.efi could not be found.
  • ms64.efi could not be installed.
  • ms64.efi could not be launched. Class not registered.
  • ms64.efi could not be started.
  • ms64.efi failed to initialize properly.
  • ms64.efi has encountered a problem and needs to close. We are sorry for the inconvenience.
  • ms64.efi is not a valid Win32 application.
  • ms64.efi is not running.
  • Cannot find ms64.efi.
  • Error starting program: ms64.efi.
  • Faulting Application Path: ms64.efi.
  • The file ms64.efi is missing or corrupt.
  • Windows failed to start - ms64.efi.
System Error


The program can’t start because ms64.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 ms64.efi error is key to properly resolving these errors. Although most of these EFI errors affecting ms64.efi 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on behalf of Microsoft Corporation, conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware.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 ms64.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.



How to Fix ms64.efi Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your ms64.efi issue. These troubleshooting steps are listed in the recommended order of execution.


Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. When you see the search box, type "System Restore" and press "ENTER".
  3. In the search results, find and click System Restore.
  4. Please enter the administrator password (if applicable / prompted).
  5. Follow the steps in the System Restore Wizard to choose a relevant restore point.
  6. Restore your computer to that backup image.

If the Step 1 fails to resolve the ms64.efi error, please proceed to the Step 2 below.

Step 2: If recently installed AOMEI Backupper (or related software), uninstall then try reinstalling AOMEI Backupper software.

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many ms64.efi error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

  1. Hit the Windows Start button
  2. In the search box, type "Update" and press "ENTER".
  3. In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
  4. If updates are available for download, click "Install Updates".
  5. After the update is completed, restart your PC.

If Windows Update failed to resolve the ms64.efi error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.



If Those Steps Fail: Download and Replace Your ms64.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 ms64.efi file version. We maintain a comprehensive database of 100% malware-free ms64.efi files for every applicable version of AOMEI Backupper. Please follow the steps below to download and properly replace you file:

  1. Locate your Windows operating system version in the list of below "Download ms64.efi Files".
  2. Click the appropriate "Download Now" button and download your Windows file version.
  3. Copy this file to the appropriate AOMEI Backupper folder location:
    Windows 10: C:\Program Files (x86)\AOMEI Backupper\msefi64\
  4. Restart your computer.

If this final step has failed and you're still encountering the error, you're only remaining option is to do a clean installation of Windows 10.


GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve ms64.efi problems. 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 ms64.efi Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying ms64.efi to your appropriate Windows system directory. AOMEI Technology typically does not release AOMEI Backupper 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 ms64.efi and all other EFI files for AOMEI Backupper. An incorrectly installed EFI file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
