I'm using windows 8 64 bit. I put it on my usb and changed the boot order so the actual program loads up fine. The problem is that nothing on the screen changes, I've left it on for 20 mins but there is no activity or progress at all.

Thank guys im gonna download it right away but one question, Do I run it with all of my ram in my computer or do test one stick at a time? Also on average how long should it take for me to know the results?
