Is there a way to make the white window not pop up?

The window tells you about a crash in the executed DOS executable. You need to take a copy of the executable and analyze it, why it crashes. You can i.e. use checked build and use yoda for debugging.
You can also attach the executed executable here, if I shoudl take a look on it.
Does the executable run properly in dosbox?

Btw, why does it display year 2568? Is it in some alternative calendar?
