How to Fix Runtime Errors in Windows 11

Runtime errors in Windows 11 can occur when an application encounters a problem while running. You might see an error message when opening a program, launching a game, installing software, or performing a specific task. In some cases, the application may stop responding or close unexpectedly.

These errors can have several causes, including corrupted application files, missing runtime components, outdated drivers, incompatible software, damaged system files, or problems with Microsoft Visual C++ Redistributable packages. The exact cause depends on the error message and the application involved.

Fortunately, Windows 11 includes several troubleshooting tools that can help you identify and resolve common runtime problems. You can restart the affected application, install pending Windows updates, repair system files, check application compatibility, or reinstall the software that is producing the error.

In this guide, you will learn practical ways to fix runtime errors in Windows 11. Start with the simpler solutions and move to the more advanced methods if the problem continues. Before making significant changes, save your work and back up important files.

Method 1: Restart the Application and Your Computer

A temporary application glitch or Windows process failure can sometimes trigger a runtime error. Restarting the affected application is a useful first step because it clears the application’s current state.

Follow these steps:

1. Close the application displaying the runtime error.
2. If the program is frozen, press Ctrl + Shift + Esc to open Task Manager.
3. Select the affected application under Processes.
4. Click End task.
5. Wait a few seconds.
6. Open the application again and check whether the error returns.

If the application continues to fail, restart your computer.

1. Save your work in any open applications.
2. Click Start.
3. Select the Power icon.
4. Click Restart.
5. After Windows starts again, launch the affected application.

A restart can resolve temporary conflicts involving memory, background processes, or application services. However, if the runtime error returns consistently, you will need to investigate the underlying cause.

Pay attention to when the error occurs. For example, if it appears only when launching one game, the problem may be related to that game or one of its dependencies rather than Windows as a whole.

Method 2: Install Pending Windows Updates

Outdated Windows components can sometimes cause compatibility problems with applications. Installing available updates may resolve issues involving system libraries, security fixes, and other Windows components.

To check for updates:

1. Press Windows + I to open Settings.
2. Select Windows Update.
3. Click Check for updates.
4. Allow Windows to search for available updates.
5. Install relevant updates.
6. Restart your computer if prompted.

After the update process finishes, open the affected application again.

You should also check whether the application itself has an available update. Software developers frequently release updates that fix crashes and compatibility problems.

Avoid downloading unofficial Windows update packages from unfamiliar websites. Use Windows Update or the software developer’s official distribution channel.

If the runtime error started immediately after a particular update, note the update’s installation date and the error details. That information may help identify the source of the problem.

Method 3: Repair or Reset the Problematic Application

If runtime errors occur only in one application, its installed files or settings may be damaged. Windows 11 provides repair and reset options for many applications, although availability varies by app.

Follow these steps:

1. Open Settings.
2. Select Apps.
3. Click Installed apps.
4. Find the application displaying the runtime error.
5. Click its three-dot menu.
6. Select Advanced options, if available.
7. Click Repair if the option is provided.
8. Restart the application and test it again.

The Repair option attempts to fix the application without necessarily removing its data.

If repairing does not help, you may see a Reset option. Resetting an application can remove its local settings and stored app data, so back up anything important first.

Traditional desktop applications may not provide Advanced options. In that situation, check the application’s own maintenance settings or reinstall it using its official installer.

If several unrelated applications are displaying runtime errors, the problem may involve a shared Windows component rather than a single application’s installation.

Method 4: Repair Microsoft Visual C++ Redistributable Packages

Some Windows applications and games rely on Microsoft Visual C++ Redistributable packages. These packages provide runtime libraries required by software built with supported versions of Microsoft Visual C++.

If a required library is missing or damaged, an application may fail to launch or display an error mentioning a runtime component or a DLL file.

To investigate this issue:

1. Open Settings.
2. Select Apps > Installed apps.
3. Search for Microsoft Visual C++ Redistributable.
4. Review the installed versions.
5. If a package offers a Modify option, open it and check whether Repair is available.
6. Follow the instructions provided by the installer.

If the required package is missing, obtain the appropriate redistributable from Microsoft’s official distribution source. Some applications require a specific version or architecture, so follow the application’s installation instructions.

Both x86 and x64 packages may be necessary on a 64-bit version of Windows because 32-bit applications can require 32-bit runtime libraries.

Do not uninstall every Visual C++ Redistributable package in an attempt to fix one error. Other applications may depend on those packages.

If the error names a particular DLL or runtime component, record the exact filename. It can provide an important clue about which dependency needs attention.

Method 5: Run System File Checker and DISM

Damaged Windows system files can cause application instability and runtime errors. Windows includes System File Checker (SFC) and Deployment Image Servicing and Management (DISM) to help repair certain system component problems.

First, open an elevated terminal:

1. Open Start.
2. Search for Terminal.
3. Right-click Windows Terminal.
4. Select Run as administrator.
5. Approve the User Account Control prompt.

In the terminal, run the following command:

DISM /Online /Cleanup-Image /RestoreHealth

Press Enter and wait for the operation to finish. It may take several minutes, and the progress indicator can pause temporarily.

Next, run:

sfc /scannow

Press Enter and allow the scan to complete.

SFC checks protected Windows system files and attempts to repair corrupted files. DISM can repair the Windows component store used for system servicing.

When both commands finish, restart your computer and test the affected application again.

If either tool reports that it could not complete the repair, note the exact message. Repeating commands without understanding the reported issue may not solve the underlying problem.

Method 6: Update Graphics Drivers and Other Device Drivers

If runtime errors occur while playing games, editing videos, using 3D applications, or performing graphics-intensive tasks, a graphics driver problem may be responsible.

Outdated or incompatible device drivers can cause applications to crash, particularly when they use specific hardware features.

To check for driver updates:

1. Right-click Start.
2. Select Device Manager.
3. Expand the relevant device category.
4. Right-click the device.
5. Select Update driver.
6. Choose Search automatically for drivers, if appropriate.

For graphics-intensive applications, you can also check the official support utility or website for your GPU manufacturer, such as NVIDIA, AMD, or Intel.

Choose a driver that matches your graphics hardware and version of Windows. If the problem began immediately after a driver update, Device Manager may offer a Roll Back Driver option.

Do not update unrelated drivers indiscriminately. Focus on the hardware or software associated with the runtime error.

If the error occurs in only one game, verify the game’s requirements and check for game-specific updates before making extensive driver changes.

Method 7: Check Application Compatibility

Older applications may not work correctly with the default settings in Windows 11. Compatibility issues can cause startup failures, crashes, or runtime error messages.

You can start by checking whether the application has a newer version designed for your operating system.

If the problem continues, try the compatibility troubleshooter:

1. Open Settings.
2. Select System > Troubleshoot.
3. Open Other troubleshooters, if available.
4. Look for the Program Compatibility Troubleshooter.
5. Run it if the option is available.
6. Follow the on-screen instructions to test the application.

You can also right-click the application’s executable file, select Properties, and open the Compatibility tab if it is present.

The compatibility options may include running the program with settings designed for an earlier version of Windows. Use these settings only when appropriate for the application.

Compatibility mode will not repair every runtime error. Missing dependencies, corrupted files, and unsupported software may require different solutions.

If the application is very old and no longer supported, check with the developer for a Windows 11-compatible release before relying on compatibility workarounds.

Method 8: Reinstall the Application

If none of the previous methods resolves the runtime error, reinstalling the affected application may help. This can replace damaged program files and restore missing application components.

Before uninstalling, back up important documents, saved projects, configuration files, and game saves if the application stores them locally.

Follow these steps:

1. Open Settings.
2. Select Apps > Installed apps.
3. Find the affected application.
4. Click the three-dot menu.
5. Select Uninstall.
6. Follow the instructions to remove the application.
7. Restart your computer if necessary.
8. Download a fresh installer from the official developer.
9. Install the application again.
10. Launch it and check whether the runtime error has disappeared.

Avoid downloading software from unofficial websites, especially if the installer promises to replace individual DLL files or fix all runtime errors automatically.

If reinstalling the application does not help, record the exact error message, the application’s version, and when the problem occurs. This information can help determine whether the issue is related to Windows, a missing dependency, a driver, or the application itself.

Conclusion

Runtime errors in Windows 11 can occur for many reasons, including corrupted application files, missing runtime libraries, outdated drivers, compatibility problems, and damaged Windows components. The best solution depends on the error message and whether the issue affects one application or multiple programs.

Start by restarting the affected application and installing available updates. If the problem continues, repair the application, check its Visual C++ dependencies, run DISM and SFC, and update the relevant drivers. Compatibility troubleshooting or reinstalling the application may help when simpler methods fail.

Avoid downloading individual DLL files from unofficial websites or removing shared runtime packages without a clear reason. These actions can introduce security risks or cause additional application problems.

If none of the methods works, use the exact runtime error message to narrow down the cause. A specific error code, DLL filename, or application name is often more useful than treating every runtime error as the same problem.
