Free Trial version Photoshop CS3 downloaded but not opening

I downloaded the free trial version for Photoshop CS3 on my computer ( windows vista), it completed installation and a folder wsas placed on my desktop for Abobe CS3 but when i click on it nothing happens, it opens up a window with several folders like Setup and Winbootstraper. How do I get this free trial to start working???

What is on your desk top is the installer.

Now you have to run that.
