When booting up the computer, have you ever received an error message indicating like the following one, inside a box titled Microsoft.NET Framework?
“Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately.”
This is quite a common error message that may happen in all Windows-based operating systems and stops you from running the computer and programs properly. But why does this unhandled exception error message happen and what should you do?
In many cases, the “Unhandled exception has occurred in your application” error messages will happen when some system file were missing or corrupted; so when getting the error message, you should perform the steps below to re-register the file causing the unhandled exception error on your system.
*Click Start, All Programs, Accessories, right-click Command Prompt and then select “Run as administrator”.
*Type these commands one by one exactly as shown below and follow the on-screen steps to go:
Regsvr32 “%ProgramFiles%\Windows Sidebar\sbdrop.dll”
Regsvr32 “%ProgramFiles%\Windows Sidebar\wlsrvc.dll”
*Reboot your computer to see whether the error message has disappeared or not.
If the above steps does not solve the problem, you should manually remove and reinstall .NET Framework with the following tips:
* Click Start, and then click Control Panel.
* Double-click on Add or Remove Programs.
* Find each version of the .NET Framework that is already installed on the computer. Then, uninstall all the versions of the .NET Framework.
*When you are prompted, restart the computer to completely remove them.
Then, download and install a new .NET framework. If the current version does not work after repairing, you need to download the latest one in Microsoft official website and install it in your computer. After you install a new copy of NET framework, I believe you will in many cases find the “Unhandled exception has occurred in your application” error message disappear immediately.
If the above steps do not work, you have to check and fix some error existing on your computer itself. And the first one you have to do is to make sure that the computer is clean from some unknown threats. We all know that computer virus is a small program which is designed to infect an operating system for damaging or corrupting data, changing data, or degrading your computer performance by utilizing resources such as memory or disk space. What is more, they are able to get onto the computer secretly without the permission of the PC users and do whatever they want. When some files are mis-removed from the PC and the system cannot load them correctly, you will fail to boot up the computer and get a “Unhandled exception has occurred in your application” error message when trying to boot up the computer or launch a certain program. Just run your antivirus antispyware program to thoroughly scan and remove all PC threats right now.
The final leading cause of “Unhandled exception has occurred in your application” error message is some problems with the Windows registry. We know that the registry is like a giant index which tells the operating system where everything is located, what resources it uses, and what settings to use when running it. That is to say, no matter which program you want to launch on the PC, it will first recall the registry database for corresponding entries. If part of the registry is corrupt and cannot be correctly read, you will start to get the dreaded blue screen of death or even cannot shut down the computer. It is very easy for you to fix these errors by running a registry repair tool regularly. These tools are designed to thoroughly scan and remove all errors inside the registry database, returning you an error-free system within clicks.
I think, there is no need for you to worry too much when getting an error saying “Unhandled exception has occurred in your application”. Instead, you should thank for it as it indicates some errors which will permanently damage the computer if cannot be repaired timely. Thus, no matter whenever you find the error message appears, take immediate actions to troubleshoot & fix it as quickly as you can.
