The problem is that I have not the faintest insight into .Net. This is an application written in a language I don't know, using a class library I don't know, using a compiler I don't know. And the executable isn't even a Cygwin application so it doesn't call Cygwin functions. So I have no idea what problem this application has. What on earth is it trying to tell me?
