What Causes the “Unhandled Exception has Occurred in your Application” Error on Windows?
There are several simple causes of this problem and the problem can be effectively tackled if you are able to recognize your scenario simply based on identifying the correct cause. Check out the list below:
Solution 1: Install every pending Windows Update
One of the most common causes that will end up causing the “An unhandled win32 exception occurred‘ error is an application that was built for the x64 platform using the MSVCR90.DLL that ends up calling the strncpy function. In this case, an access violation triggered in Msvcr92.DLL file will most likely cause the application to stop responding in the strncpy function. An exceeding source buffer or an improper final byte are the most likely causes of this issue. Fortunately, Microsoft is already aware of this issue and has released a hotfix for this issue that will automatically resolve it. To take advantage of it, all you need to do is update your OS version to the latest version available.

Solution 6: Install the Latest Version of NET Framework and Repair it

Solution 7: Perform a Clean Boot
There are various other programs and services which can affect the proper functionality of the Microsoft .NET Framework suite.
