Got the McUICnt.exe Error? Here‘s Your Step-by-Step Guide to Fixing It

Have you ever gone to open your McAfee antivirus only to be greeted by an intimidating error message like "McUICnt.exe – Entry Point Not Found"? I‘ve been there before, and I know how frustrating it can be when your antivirus stops working right after an update.

Not to worry though – I‘ve got your back! In this detailed guide, I‘ll walk you through exactly why you‘re seeing this error, and the steps to get McAfee back up and running quickly.

By the end, you‘ll be able to confidently troubleshoot and resolve the McUICnt.exe error yourself. So let‘s get started!

Why Does "Entry Point Not Found" Happen in McAfee?

First, let‘s quickly cover what‘s behind this obscure sounding error. The full message often says something like "The procedure entry point BCryptHash could not be located in the dynamic link library bcrypt.dll."

The key things to understand are:

Entry Point: This refers to a specific function McAfee needs to run that is contained within a DLL file.
DLL: A DLL (Dynamic Link Library) is a collection of functions and resources that Windows programs rely on.
Not Found: The DLL file that contains the function McAfee needs is missing or corrupted.

McAfee uses many DLL files with functions that it calls on when operating. If one of these DLLs is damaged or goes missing, McAfee throws the "entry point not found" error when it tries to look for a function that isn‘t there.

This happens most often after updating McAfee, which can overwrite or unlink required DLL files. Based on McAfee community forums, it seems over 10% of users updating to the latest definitions experience this error.

The good news? It‘s easily fixed by replacing the missing DLLs and reinstalling McAfee to clean out any corrupted files.

Which McAfee Products Are Affected?

Before we jump into the steps, it‘s useful to know which McAfee consumer antivirus products commonly see this error:

Product	Versions Affected
McAfee AntiVirus	2016 and later
McAfee LiveSafe	2016 and later
McAfee Total Protection	2016 and later
McAfee Security Scan Plus	Latest version

So if you use any of those suites and encounter the McUICnt.exe error, the troubleshooting steps I‘m about to walk through will apply.

Step 1: Download the Latest DirectX and Visual C++

Many missing DLL file errors can be resolved by installing the most updated versions of DirectX and Visual C++ Redistributable.

DirectX is a collection of APIs and components needed for graphics, sound, and other multimedia functions on Windows. The latest DirectX includes many common DLLs that might be missing or corrupted.

You can download it directly from Microsoft here:

Visual C++ Redistributable contains runtime components needed for programs built in Visual Studio. Like DirectX, it includes many shared DLLs that might fix the one reported missing.

Get the latest x64 version here:

https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170

Installing these two updates will replace a lot of the DLLs that could be causing the McAfee error. If the installations ask to reboot, go ahead and restart your computer.

Once your system is back up, try opening McAfee again to see if the error persists before moving on to the next steps.

Step 2: Fully Uninstall and Reinstall McAfee

If the DLL updates didn‘t fix the issue, it‘s time to completely remove McAfee using the official McAfee Consumer Product Removal tool.

This will wipe McAfee off your system and delete any corrupted files or registry entries that could be causing problems.

You can download the MCPR utility here:

Open and run the MCPR tool, following the on-screen instructions:

Agree to the license terms
Select your McAfee product
Click "Remove"
Restart your computer if prompted

This will cleanly uninstall McAfee and all its components.

Now head over to the McAfee site to reinstall the latest version:

With the slate wiped clean, this should resolve any lingering corrupted files causing the "entry point not found" error.
