Windows XP (perhaps SP2) self included file extraction also does ISO files.

>Can someone tell me why this brilliant idea was released? I mean, what is it with the idea of using ISO file to VFP 9 download setup? I've been trying to figure out for 30 minutes how to get something out of that file. I have B's Recorder Gold CD writer software. So, so far, I succeeded to create an IMG file from the original file. Then, I need to find a way to dump that image into a regular CD. Then, I need to run it from the CD. Why is that so complicated?
