zechs is right - I bought an upgrade from Raydream 4 to Carrara Studio at a huge discount from Eovia, but Carrara showed up full... I was able to ditch Raydream from my machine without a problem. Believe it or not, the "Upgrade" versions of Win95, 98, and even 2k are "full" versions... just that M$ requires seeing something owned by Microsoft on the hard drive, or it will ask you to stick a disk in. I have an old old old copy of MSDOS 5.0 I used in conjunciton with that :) /P
