MMC Could Not Create the Snap-In error is commonly observed. MMC or Microsoft management (MMC) console is an application service that provides users with a graphical user interface. It is also a capable programming framework. This enables some tools or software consoles with administrative privileges to open and execute. MMC was released way back in the days on Windows 98 and has been carried over in all versions released since.

It is essentially a tool host comprising of necessary components called snap-ins. This means that it does not have its built-in management tools, but it simply provides frameworks for its design and development. MMC is just like windows explorer, where you open multiple instances of files or different files altogether. You get the implementation of Multiple Document Interfaces or MDI with the MMC tool.

Sometimes, these snap-ins might act abnormally and not give you the results that you were expecting, and throw you an error that says something like MMC could not create the snap-in. It happens on pretty much all computer systems, especially Windows PCs.

So, we can either be ranting about it and smash our system. Or we can try to think of a solution that does not involve making the PC our punching bag. I have managed to compile two highly effective methods to fix the MMC that could not create the snap-in Windows 10 error message. Let’s start then, shall we?

How to Fix MMC Could Not Create the Snap-In

Follow these simple methods to learn how to fix the error:

Method 1: Turn on .Net Framework

Sometimes, the MMC might not install correctly, or maybe, it might be missing the support which is typically provided by the Microsoft.Net framework. It is usually preinstalled on your Windows operating system.

Unless you have uninstalled it yourself, you need not be concerned about reinstalling it for this purpose. To enable the Microsoft.Net framework, follow these simple steps:

1. Enter the Control Panel by right-clicking on the Windows/Start button and selecting Control Panel. You can also go by searching for control in the Run menu (Win+S).

2. Once you are in the Control Panel, you need to click on Programs.

3. Now, we select the Turn Windows features on or off option found under Programs and Features.

4. Then, choose Microsoft.Net Framework 3.5 option. You will have to expand each one of the components and check the tick boxes next to the items. The items that you want to turn on. Items such as the Windows communication foundation HTTP Activation.

5. Click on OK and Apply the changes that you made. Restart the computer for good measure, and check and see if the MMC issue has been fixed or not.

Method 2: Fix Your Registries

Registry files are essential for storing key values of specific software modules in your system. But sometimes, they get scrambled and corrupted. It is due to overwriting of new values on top of the older ones for some software tools.

This causes a ton of issues with your system. It might also lead to MMC could not create the snap-in error. How about we clean those registry files and see if it makes a difference? Here is how you can do that:

1. At first, go to the Run menu by pressing the Windows + R keys. Then type “regedit” in the Run window’s text box. Click OK to open the Windows system’s built-in Registry Editor.

Type regedit
Type regedit

2. Once the registry editor opens up, you need to navigate to the following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MMC\SnapIns

3. Afterward, inside the folder named SnapIns, you have to search for the error number specified in the CLSID. You can find it in the error box itself.

4. The MMC could not create the snap-in error prompt will have a small text field named CLSID. CLSID will have some weird looking text like FX:{b05566ad-fe9c-4363-be05-7a4cbb7cb510}. You need to navigate to that particular error code in that directory.

5. After navigating to the CLSID key, you have to right-click on the CLSID FX:{b05566ad-fe9c-4363-be05-7a4cbb7cb510} and select the Export option. It will let you back up that particular registry key into a file with a .reg extension. After that, just right-click on the same key again, and this time, select the Delete option. Since we already have a backup, we don’t need that registry copy anymore.

6. Finally, when you get the confirmation box, click Yes. It will delete possibly faulty and corrupt registry keys permanently. Close the Registry Editor window, and reboot your PC for good measure.

Don’t worry about the deleted registries. Because after you restart the PC, Windows operating system will automatically generate the required registry keys. The keys for the Event Manager and this should, hopefully, solve the problem. So, when you open up the Event Viewer app, it must work as expected.
