What are CEFReg.exe Error Messages?

CEFReg.exe Runtime Errors

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

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

Some of the most common CEFReg.exe errors include:

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

System Error

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programming on behalf of McAfee, Inc., conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware.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

How to Fix CEFReg.exe 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 CEFReg.exe 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):

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

If the Step 1 fails to resolve the CEFReg.exe error, please proceed to the Step 2 below.

Step 2: If recently installed McAfee Total Protection (or related software), uninstall then try reinstalling McAfee Total Protection software.

You can uninstall McAfee Total Protection software by following these instructions (Windows XP, Vista, 7, 8, and 10):

Hit the Windows Start button
In the search box, type "Uninstall" and press "ENTER".
In the search results, find and click "Add or Remove Programs"

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 CEFReg.exe error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

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

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

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

CAUTION : We strongly advise against downloading and copying CEFReg.exe to your appropriate Windows system directory. McAfee, Inc. typically does not release McAfee Total Protection 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 CEFReg.exe and all other EXE files for McAfee Total Protection. An incorrectly installed EXE file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
