You can't just write a small command script that starts Infernal Explorer with an URL to your program?

Brute force and ignorance -- don't underestimate it! :-)

If you can't do that, it will be a bit of bother. You need people to install Perl. (-: Arguably, not a bad thing. :-)

Let your program generate a temporary file and start Internet Explorer with that file.

Someone that knows more than me about Windows and Win32::OLE are sure to expand on this ignorant newbie's post with more explicit advice on how to (a) find the temp dir on Win and (b) how to start Internet Exploder.

Update: I assume above that the form parameters can easily be translated to command line parameters. The other answers assumes the configuration is too complex for that? If so, a small http server might be the best choice to translate your program fast (you need to copy/paste sequences, I guess?).
