How to Fix “Unhandled Exception Has Occurred in Your Application”

If you’re seeing an “unhandled exception has occurred in your application” error

If you’re seeing an "unhandled exception has occurred in your application" error on your Windows PC, we’ll show you solutions you can use to fix it here.

If you’re running apps or gaming on your Windows computer, you might encounter an "unhandled exception has occurred in your application" error.

This error is tied to the Microsoft .NET Framework, but it could also be caused by corrupt apps or system files. Luckily, we have some options you can use to fix the "unhandled exception has occurred in your application" error below.

One of the first places to start resolving the problem is by running the .NET Framework Repair tool, which will detect and repair frequently occurring issues with the .NET Framework or its updates.

To run the .NET Framework repair utility:

If you are still experiencing the error after running the repair tool, make sure that all versions of the .NET Framework are enabled on your system. If they’re not installed, it can cause the unhandled exception error to occur.

To enable .NET Framework on Windows:

Keeping your Windows PC is vital to ensure you have the latest security and feature updates. It also provides bug fixes that could be at the root of the error. So, you can manually check for Windows Updates and install any fixes it finds.

Open Settings > Windows Update and click the Check for updates button. Note that a restart may be required to install the latest fixes.

In addition to problems with .NET or corrupt files, your system could be infected with a virus or other malicious code. For example, Windows 11 has its own Windows Security feature built-in, but it never hurts to scan your system manually.

Launch Windows Security from the Start menu, select Virus & threat protection, and run a Full scan.

Regardless of what it does or doesn't detect, this is a perfect opportunity to set up Windows Security for maximum protection to prevent future virus and malware attacks.

Also, if you want a second opinion, run a free third-party AV program like AVG Antivirus or Avast to see if it discovers a problem and follow its onscreen instructions for removal.

You can fix the problem by running SFC and DISM scans if the error is caused by corrupt system files. Each scan will identify and fix these files. It's typically best practice to run an SFC scan first, followed by a DISM scan.

To run the SFC scan on Windows 11:

Note that these scans can take a while to complete. The amount of time varies between systems, so ensure you allot time for the scans to execute and complete. After running both scans, check if you still have problems with the error in the problematic app, game, or file.

When you see an "unhandled exception has occurred in your application" error, fixing the .NET Framework is typically the best way to fix it. However, if it's caused by corrupt system files or malicious code, you can use the other options above to fix the error and get back to work.

While Windows 11 runs well compared to previous versions, problems will crop up periodically that you’ll need to troubleshoot. For example, check out how to fix an Unidentified Network error. Or, you may need to fix network sharing not working on Windows 11.
