Every time I attempt to install Vegas 7.0 on a platform running MS Media Center Edition (MCE) the load attempt fails and informs me the serial number as being invalid. As a test to assure the software disk is not corrupted, I have installed and uninstalled Vegas 7.0 using the same media successfully on platforms running XP Pro. I am not sure if my internal MCE settings are incorrect or if Vegas, flat-out, is incompatible with MCE. Any thoughts out there?
