A good start is to check that all the files required to run DJGPP are in the correct
place. If DJGPP is correctly installed, you know where it is installed because there
is a SET DJGPP=... statement in your autoexec.bat. Look in that directory and search
each subfolder for the relevant files.

You'll need to search every file on the hard disk until you find it. This is not so
hard as there are some good ANSI commands for precisely this purpose. You should
allow the user to select where they think the file is, and the search starts from
there. If that fails, you search the rest of the partition, then the rest of the
installed drives (remember that some people run DJGPP straight from CDROM).

st the BIN directory.
But what you have should work. The only thing I can think of is that you havn't got
all the files required. Check the ZIP PICKER at www.delorie.com/djgpp and see if you
have installed all the files you need.
