"The setup program is running from the TEMP directory. That should already set off alarm bells. "
They are dumb, didn't you tell them that Ray? I mean, you make a product, create a nice site around it and users all over the world will start taking the installer from your site and give it a try. The very first thing they would is to test that case. Every major browser will allow you to "Run/Open" / "Save" the installer from your site. And most users will press "Run/Open". That means the browser will download the installer into TEMP directory and then launch it from there. What did they expect? 90's? to ship the CD via air-mail so the installer starts from a clean directory? Tell them you're still working on that time machine.
