What is the difference between Data Studio and Boot Disk?

The two utilities are similar, however Active@ Data Studio has more functionality than Active@ Boot Disk.

Active@ Boot Disk is an ISO image only (with a Bootable Disk Creator utility for easy media creation).

So if you want to run any of the programs, you always have to boot up your computer from the ISO bootable image (Bootable CD or USB flash stick).

Active@ Data Studio is a fuller package that contains all the same programs as Active@ Boot Disk, which can ALSO be run within regular Windows (as regular desktop applications) and also have the option of booting up from the bootable CD or USB flash stick.
