Hello everyone. I'm posting this thread because i want to know how to install XP on Windows 7 Ultimate. I tried a few methods now, VMWare Workstation 9 doesn't work because when i install XP VMWare gives me an error saying that kernel couldn't be found or some dumb **** like that. (excuse my language) I tried downloading VMWare Player and i can't install it because it asks me to delete VmWare Workstation 9, I'm not going to do that because I have Mountain Lion 10.8 Installed on it. And last but not least I tried using " Windows Virtual PC " on the official website. When i click download they say that they have to check weather my copy of windows is genuine or not. It checked, and told me that it was not. And it was. My license key was real. So it kept giving me the damn error that i need a new activation code so i had to use a " remove wat " program. Anyways " Windows Virtual PC " is also out of the picture. Anyone else has an idea? Perhaps another Virtual Machine for PC? Thanks for looking.
