Ok, I've installed windows on my macbook using parallels. I registered windows and parallels online. I tried to install my new favorite computer game wolfenstein 2. But when i put the cd in, it loads up the install splash screen. I click install and it says " setup launcher has encountered a problem and needs to close. We are sorry the inconvenience." as an error report and says send to Microsoft or dont send. So how do i fix this or is there anything i can do ? I'd really like to get back to my gaming.
