Guide: Fix ‘Unhandled Exception Has Occurred’ Issue in Windows 10
The ‘unhandled exception has occurred’ error is not associated with a particular app, making it much more difficult to resolve. Some users also see an error: An unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and try to continue. Clicking Exit will close the application immediately. If you see this error while using a particular app, then you should start troubleshooting that app. But how? There are a few ways to fix that error as we’ll cover below. By the end of this guide, you should be able to work normally without seeing annoying pop-ups. Let’s start.
1. Update the operating system and apps
We will start by updating Windows 10 to the latest version. That can fix quite a few bugs in the system. Press Windows Key + I to open Settings and click on Updates & Security.
Under Windows Update, check for updates and, if any, update and restart your computer once.
Since this error usually occurs when using a particular app, you should update that app immediately. If you’re using the Windows Store, open it and click the Download icon to find and install app updates.
Restart your computer and check if you continue to see the error.
2. Scan for malware
Windows Defender runs in the background to scan for malware. If you’re using a third-party app, open it and run a full system scan. If anything is found, follow the on-screen instructions. Download Malwarebytes from the link below and run a full scan again.
In case you don’t know, viruses and malware are two different things, and Malwarebytes is designed to be used in conjunction with an antivirus program. The free version is good enough in most cases. Download Malwarebytes
3. Troubleshoot
Windows 10 comes with a built-in troubleshooting option that can be used to find and fix various errors in Windows and Microsoft apps. Not for third party apps. Press Windows key + I to open Settings and search for ‘Troubleshoot Windows Store apps’ and select Find and fix problems with Microsoft Store apps.
Follow the on-screen instructions from here, which is easy. Let it do its job. If it finds something, it will try to fix it itself or provide a solution.
4. .NET Framework
Have you installed .NET Framework on your computer? It is free software from Microsoft that compiles and runs programs written in different languages. It provides interoperability between different coding languages. Do not you get it? Just click on the link below to download and install the latest version.
When in doubt, choose the recommended version, which should also be the most stable version. Restart your computer and check if you still get the “unhandled exception has occurred” error. If you already have it on your computer then I recommend that you update it to the latest version. Please check the system requirements before downloading. Download .NET Framework
5. Run the .NET Framework Repair Tool
While there are third-party apps in the market for you to try, I recommend that you use the official Microsoft repair tool first. Download and install the app from the link below and see if anything is found. Reboot when you are ready to check again.
Aaron Stebner, a Microsoft engineer, wrote a detailed guide on using his version of the repair tool as ‘the last resort’. The steps are very advanced and are beyond the scope of this guideYou can find more details here, but if you really know what you’re doing, follow along. The guide was written back in 2008, but has been updated to support the latest versions of the .NET Framework. Download .NET Framework Repair Tool
6. Remove / reinstall .NET Framework
Yes, this error is often associated with .NET Framework. In fact, due to the complex nature of this software, it has been subject to many errors since its introduction in 2002. Users with Windows 8 or higher should skip this step as it is not possible to uninstall .NET Framework on later versions.
Open Control Panel and click Uninstall a program. You will see a list of all the apps installed on your computer here. Find the .NET Framework here, and there may be more than one. So right click on it and choose Delete.
Reinstall using the download link shared in section 4.
7. SFC scan
System File Scan or SFC searches for corrupt files and repairs them for you. If the ‘unhandled exception error’ is due to a corrupted file, SFC scan is your best bet. To do this, open the command prompt with administrator privileges and type the command below. sfc / scannow
8. Clean boot and safe mode
We have written a detailed guide on both topics, including how to carry them out. Follow the steps and see if you can fix the error this way. Start with Clean Boot first and then go to Safe Mode.
Treat it
Due to the complex nature of the .NET Framework, it can be a bit difficult to fix this error as this is the source in the first place.
