Exit code 255 sounds like a .NET exception within the tool (target application) you’re running. You’ll not be able to catch this exception in your code.
I would register a debugger for the target application to see what exception it throws:
- Go to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options
- Create a key with the name of the executable you’re starting
- Create a string called
Debugger
- Give it a value, e.g.
vsjitdebugger.exe
if it’s a .NET application
This will start the debugger and you can catch exceptions.
