How to open external file from Flash *.exe application

Hello!

In my Flash application users must be able to download or open PPT files nested in application’s subfolder.

When I run .*swf file, it works fine (Save file dialog appears), but if I run .exe file, nothing happens.
This is the code:

 
var fileUrl:String = "templates//601.ppt";
var request:URLRequest = new URLRequest(fileUrl);
navigateToURL(request, "_blank");

I suspect that “navigateToURL” function doesn’t work in this case. Could you suggest me something?

Thank you for advance!
