MMC.exe Application Error and its causes

Corrupt system files

MMC.exe Application Error can often occur due to corrupt system files. When critical files required to run Microsoft Management Console (MMC) become damaged or missing, it can lead to this error.

Corruption can happen due to improper installations, malware infections, or even sudden power outages.

Issues with the disk

Sometimes, the error can be attributed to issues with your disk. A failing or fragmented hard drive can cause MMC.exe Application Error.

Disk errors can occur when sectors on the disk fail, leading to data corruption and malfunctions when running certain applications or processes.

Missing permissions

Lack of necessary permissions can also trigger MMC.exe Application Error. If your user account does not have the required administrative rights to access and run MMC, you may encounter this error.

It can happen due to changes in user permissions, accidental modifications, or malware attacks. Quick fixes for MMC.exe error

Restart the computer

One of the simplest and often effective solutions is to restart your computer. This helps in clearing temporary system glitches that may be causing the MMC.exe Application Error.

Restarting your system refreshes system resources and can resolve issues that might be interfering with the proper functioning of MMC.

Check for Windows updates

Keeping your Windows operating system up to date is crucial for the smooth functioning of various applications. To check for updates, open the Windows update settings and click on “Check for updates.” Installing the latest patches and security updates can fix any known issues with the Windows system files, including those related to MMC.

Remember to re-enable it after troubleshooting to maintain system security.

Administrator account login

If the MMC.exe Application Error persists, it’s worth trying to launch MMC using an administrator account. Administrators typically have the necessary permissions and access rights to resolve such issues.

To run as an administrator, right-click on the MMC shortcut and select “Run as administrator.”


By understanding the causes of the MMC.exe Application Error and employing the quick fixes discussed above, you can overcome this frustrating issue and get back to smoothly managing your system tasks. Remember to always maintain a healthy system by keeping your software updated, performing regular disk maintenance, and implementing security measures to prevent future errors.

With these solutions in your troubleshooting toolkit, you can tackle any MMC-related challenges that come your way!

Solutions for fixing MMC.exe error

Launch the app from an elevated Command Prompt

If you’re encountering the MMC.exe Application Error, launching the application from an elevated Command Prompt can help resolve the issue. An elevated Command Prompt allows you to run commands with administrative privileges, giving you the necessary permissions to access and execute MMC successfully.

Here’s how you can do it:

1. Press the Windows key and search for “Command Prompt.”


Right-click on the Command Prompt icon and select “Run as administrator.”

3. In the Command Prompt window, type “mmc” (without quotes) and hit Enter.

Launching MMC through an elevated Command Prompt may bypass any permission-related restrictions and provide a temporary workaround for the application error. Run the DISM, SFC, and Check Disk scans

MMC.exe Application Error can also be caused by corrupt system files.

Running the Deployment Image Servicing and Management (DISM) tool, System File Checker (SFC) scan, and Check Disk scan can help identify and repair such issues. 1.

Open an elevated Command Prompt as described in Subtopic 3.1.

2. Type the following command and press Enter:

DISM.exe /Online /Cleanup-image /Restorehealth

This command will scan your system files, check for corruption, and try to repair them if necessary.

3. Once the DISM scan is complete, type the following command and hit Enter:

sfc /scannow

The SFC scan will check the integrity of your system files and replace any corrupted files with a cached copy.

4. After the SFC scan finishes, run a Check Disk scan to identify and fix potential disk errors:

– Press the Windows key, type “Command Prompt,” right-click on it, and select “Run as administrator.”

– In the Command Prompt window, type “chkdsk /f /r” (without quotes) and press Enter.

– You may be prompted to schedule the scan for the next system restart. Type “Y” and press Enter.

– Restart your computer, and the Check Disk scan will run during the startup process. Running these scans can help resolve any system file or disk-related issues that might be causing the MMC.exe Application Error.

Modify the Local Security Policy

If the MMC.exe error still persists, modifying the Local Security Policy settings may help. Follow these steps:


Press the Windows key, type “Local Security Policy,” and open the corresponding application. 2.

In the left-hand pane, navigate to Security Settings > Local Policies > Security Options. 3.

Look for the policy “User Account Control: Run all administrators in Admin Approval Mode.”

4. Double-click on the policy and select “Disabled.”


Click on OK to save the changes. This modification disables User Account Control (UAC) for administrators and may resolve the MMC.exe Application Error.

However, note that turning off UAC carries some security risks, so exercise caution and enable it after troubleshooting.

Disable UAC

Another potential solution is disabling UAC temporarily. Here’s how:


Press the Windows key, type “UAC,” and click on “Change User Account Control settings.”

2. Move the slider to the “Never notify” position.

3. Click on OK and restart your computer.

Disabling UAC can help mitigate any permission-related issues and potentially resolve the MMC.exe Application Error. However, similar to the previous solution, re-enable UAC after troubleshooting to maintain optimal system security.

Repair Microsoft Visual C++ Redistributable

The MMC.exe Application Error may also stem from issues with the Microsoft Visual C++ Redistributable package installed on your system. To repair it:


Press the Windows key and search for “Control Panel.”

2. Open Control Panel and click on “Programs” or “Programs and Features” depending on your Windows version.

3. Locate “Microsoft Visual C++ Redistributable” in the program list.

4. Right-click on each version (starting with the most recent) and select “Repair.”


Follow the instructions provided by the repair wizard to complete the process. Repairing the Visual C++ Redistributable package can fix any compatibility issues that might be causing the MMC.exe error.

Uninstall recent updates

In some cases, recent updates of Windows or other software can trigger the MMC.exe Application Error. Uninstalling these updates may help resolve the issue.

Here’s how:

1. Press the Windows key and search for “Control Panel.”


Open Control Panel and click on “Programs” or “Programs and Features.”

3. Click on “View installed updates” on the left-hand side.

4. Locate the recently installed updates (sort by “Installed On” to find them easily).

5. Right-click on each update and select “Uninstall.”


Follow the on-screen instructions to complete the uninstallation process. After removing the updates, restart your computer and check if the MMC.exe error persists.

If not, you can choose to delay the installation of those updates or check for updated versions.

Perform an in-place upgrade

If none of the previous solutions work, performing an in-place upgrade of your Windows operating system can be a final troubleshooting step. This process repairs the system by reinstalling Windows while keeping your files intact.

1. Backup your important files to an external storage device or cloud service.

2. Visit the official Microsoft website and download the Windows Media Creation Tool.

3. Run the Media Creation Tool and select “Upgrade this PC now.”


Follow the on-screen instructions to perform the in-place upgrade. Note that this process may take some time, and you may need an active internet connection to download the necessary files.

By employing the solutions discussed above, you can troubleshoot and fix the MMC.exe Application Error, ensuring a smooth and uninterrupted user experience with your Microsoft Management Console.
