In add/remove programs->on the left there is a Add/Remove Windows components. It's usually there. I installed MP10 on Duron 750Mhz, Duron 1.1GHz, Pentium 3 600Mhz. So I guess it's not the old CPU. Something else - maybe any other component of Winboze. Anyways - MP is not that good at all

you have plenty of other great player to use

Cheers
