After installation goes right back to installation
 

After I install Snow Leopard, using iAtkos S3 version 2, my computer does the mandatory restart, and after that, regardless of what I do, it goes right back to the beginning of the installation, asking me to install it again. I don't know what is causing it or how to fix it.

I have a Gateway 838GM with 1.5 GB of RAM and a clean 80gig HD. I am trying to run the installation in 32-bit mode so that it runs on my computer but it refuses to work.

What can I do?

Thank you for your help ahead of time. :)

Did you remove the DVD from the drive?
