So it fails when it tries to create a response file.

One idea is to put a call to `getch' conditioned by the specific way
that it fails.  When getch is called, the program is put on hold until
you hit a key.  I'd then suggest to open another DOS box and look
around in the directory where it tries to create the response file.
Are there any files there? how many? is dj410000 one of them? can you
create a file by that name in the same directory with some other
program, like `touch'?
