The Microsoft Management Console (MMC) is an application that facilitates a graphical user interface (GUI) and a programming framework for creating, saving, and opening consoles containing administrative tools. It has been included in all subsequent versions as part of the Windows 98 Resource Kit.
Employing a Multiple Document Interface (MDI) akin to Windows Explorer, MMC acts as a container rather than a provider of management tools, often termed a “tools host.” Occasionally, certain snap-ins may malfunction, particularly if their registry configuration is flawed (excluding the Registry Editor).
This results in a specific error message, such as “MMC could not create the snap-in. The snap-in might not have been installed correctly,” notably observed with the Event Viewer.
Fixing “MMC Could Not Create The Snap-in” Error
Before proceeding, it’s essential to create a system restore point. This precautionary step ensures that you can restore your system to its previous state if anything goes wrong. Now, without further delay, let’s explore how to resolve the “MMC Could Not Create The Snap-in” error using the troubleshooting guide below:
Method 1: Enable the Microsoft .NET Framework
- Use Windows Search to find the Control Panel, then select “Control Panel” from the search results.

- Within Control Panel, locate and click on “Uninstall a program” under the “Programs” category.

3. Next, choose “Turn Windows features on or off” from the options available on the left-hand menu.

4. Locate “Microsoft .NET Framework 3.5” from the list. Expand each component and check the ones you wish to enable.

- Restart your computer and check if the issue is resolved. If not, proceed to the next step.
- If the issue persists, rerun the System File Checker tool.
Following the above steps may resolve the “MMC Could Not Create The Snap-in” error. If the issue persists, proceed to the next method.
Method 2: Run System File Checker (SFC)
- Press the Windows Key + X, then select “Command Prompt (Admin)” from the menu.

2. In the Command Prompt window, type the following command:

3. Wait for the scanning process to complete. Once finished, restart your PC.
4. Open Command Prompt again and type the following commands one by one, pressing Enter after each:

5. Allow the DISM command to run and wait for it to complete.
6. If the DISM command does not resolve the issue, proceed to the next step:
7. Reboot your PC to save the changes and check if the “MMC Could Not Create The Snap-in” error is resolved.
Method 3: Registry Fix
- Press the Windows + R keys simultaneously, then type “regedit” in the Run dialog box and press Enter to open the Registry Editor.

2. Within the Registry Editor, navigate to the following key:

3. Within the SnapIns key, locate the entry corresponding to the error number specified in the CLSID.

4. Once you’ve located the key corresponding to the error number (FX:{b05566ad-fe9c-4363-be05-7a4cbb7cb510}), right-click on it and choose “Export” to create a backup of the Registry key as a .reg file. Then, right-click on the same key again and select “Delete” to remove it.

5. Confirm the deletion of the registry key by selecting “Yes” in the confirmation dialog. Close the Registry Editor, then restart your system.
After the reboot, Windows will automatically regenerate the necessary registry configuration for the Event Manager, resolving the issue. You can then open Event Viewer and verify that it functions as expected.

Method 4: Installing Remote Server Administration Tools (RSAT) on Windows
If none of the previous methods resolve the issue, you can utilize Remote Server Administration Tools (RSAT) as an alternative to MMC on Windows 10. RSAT, developed by Microsoft, is a valuable tool for managing Windows Servers remotely. It includes MMC snap-ins like “Active Directory Users and Computers” that facilitate remote server management. These snap-ins function as add-ons to the RSAT module, enabling users to make changes and manage remote servers effectively. RSAT is particularly useful for tasks such as adding new users and resetting passwords within organizational units. Let’s proceed to learn how to install RSAT on Windows 10.

Frequently Asked Question
