When installing Macromedia ColdFusion MX on a Windows system that uses hyperthreaded processors, you may receive a warning telling you that your system contains more processors than you are licensed for. Macromedia's advice: Ignore the warning, as long as you've paid for your license, as their software is based on physical, not logical, processors.
