application exception

0xE0434352 .NET_EXCEPTION

A .NET program crashed with an unhandled exception. The Windows Event Viewer usually has the detailed .NET error right next to this crash — that message is the real diagnosis.

What to do about it

Update the program.
Open Event Viewer → Windows Logs → Application and look for the .NET Runtime error logged at the same time — it names the actual failure.
Repair/update the .NET runtime from Windows Update.

Where you will see this

Windows Error Reporting writes this code into Report.wer files and app-crash minidumps when a program dies but Windows itself stays up. It is not a blue-screen stop code — for those see the stop-code library.

See which module threw this exception

Drop the program's .wer report or crash dump into the app-crash reader — the faulting module is usually the real story. Parsed locally.
