You will probably have to get specifics from a newsgroup that deals with
your compiler but there is generally a way to retain the files generated
after pre-processing. You could tell your environment to do just the
pre-processing stage and they work with the files it generates. You'd
probably want to comment out the standard header files so they don't get
pre-processed as well.

If the code is there and functional you have me stumped. I'd guess that it
is also a system specific problem. A newsgroup that deals with your
environment might be able to help you better than here.

Just a wild guess, is the file being created with an absolute path? If
not, the relative directory might not be what you expect. COM objects will
use %SystemRoot% as the current address for relative addresses.
