Since Microstudio is a single program, there is no patch we can offer. To run under XP or 2000 requires Microstudio 2.400.
We changed our software download method about 1.5 years ago from a single download (what you had access to), to up to 8 downloads to allow us to provide free upgrades.

We will start beta testing Microstudio 2.500 today. It supports some new drives and has a vastly improved Installation program. The download file will be about one-third the size (<2MB) of 2.400. If you are not in critical need, you might want to wait until we announce this release... expected within 2 weeks.
