Hey, just wondering does Halo Trial work on Parallels? and is there a way to assign ammount of proccessing power for the Virtual Machine? i have a Macbook Pro 17" 2.4 ghz and My virtual machine software is Windows XP Pro i tried to open halo trial but it said it had an error so im guessing it has to do with Parallels somehow, maybe some settings i didn't know of that i must switch on to work?
