Have you checked if the cgi program can be run in command line? Does the program have the necessary permissions in order to be ran by the user that runs the web server? Try to search that error with Google and maybe you will find something. I don't think there are too many programmers that create cgi programs in C.

I tested it on my laptop's apache server. I just setup a Apache server on another box, that does not have Visual Studio 2005 or VC++ installed on it. I feel very good about the Apache configuration file being correct. But when Igo to access the CGI file through a CGI post I get an error. I then downloaded and installed the VC++ SP1 2005 libraries straight from Microsoft and installed them on the box. Still I get the same error. Anyone have an idea? The error is pasted below from the Error.log file.
