Can you run the applications in Macromedia Studio MX 2004 under Vista Home Premium?
I believe there would be problems because Vista is written in a different way to XP. Vista locks down certain parts of the operating system and uses User Account Control to secure the system. When Studio MX 2004 was written Macromedia had no idea of the security measures that M$ would use 5 years down the line, and so the two would be likely to fight. You’d have a better chance with Adobe Creative Suite 3, which was written for Vista.
