What are EP0NCAUC.CMB Error Messages?


General EP0NCAUC.CMB Runtime Errors

EP0NCAUC.CMB file errors often occur during the startup phase of Windows, but can also occur while the program is running. These types CMB errors are also known as “runtime errors” because they occur while Windows is running. Here are some of the most common EP0NCAUC.CMB runtime errors:

Most CMB errors are due to missing or corrupt files. Your EP0NCAUC.CMB file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Windows), or deleted by a malware infection. Furthermore, EP0NCAUC.CMB file corruption could be caused from a power outage when loading Windows, system crash while loading or saving EP0NCAUC.CMB, bad sectors on your storage media (usually your primary hard drive), or 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 EP0NCAUC.CMB 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.

  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 EP0NCAUC.CMB error, please proceed to the Step 2 below.

Step 2: Run SFC (System File Checker) to restore the corrupt or missing EP0NCAUC.CMB file.

  3. Press and hold "CTRL-Shift" on your keyboard while pressing "ENTER".
  4. You'll be prompted with a permission dialog box.

Download EP0NCAUC.CMB Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying EP0NCAUC.CMB to your appropriate Windows system directory. Microsoft typically does not release Windows CMB 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 EP0NCAUC.CMB and all other CMB files for Windows. An incorrectly installed CMB file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
