I do not think so, I installed it on my older machine, and it worked fine, of course it ran a tad slower due to the fact that I only had 128mb slow SDRAM, but it looked a hella cooler. Just to note that my computer also failed several weeks later, I believe it had something to do with my hardware,about a 5 yr old machine, something had to give right? OR something about Windows Genuine Advantage, they did an update and I received a message on the bottom right corner of my screen that my windows was fake, meh.
