Running Acid pro 6.0 on a old 4gb Millenium machine

Hey I've had my computer for a while now and i'm starting to get into this music recording stuff. I have a windows xp machine downstairs but other famliy members use this as well and i don't think they want my big digital piano in their way all the time so i'm going to have to find use for my computer upstairs where my piano is. I bought a MIDI input, output to USB converter to plug my computer into my piano throught USB. So now all i need to do is find a way to somehow make the software think that its running on xp or maybe have a bootable program of xp that i could somehow install the software onto. Thanks in advance
Regard,
