I'm not sure it's ever been tested on Win2K3, but it should work. Have you tried running the setup EXE on another machine, perhaps one running XP Pro or Windows 2000? The reason I ask is we believe the corruption error and running it under Win2K3 is unrelated.
If you get an error saying the setup files are corrupt, could this be due to a virus on your side? When the setup runs, it checks itself for data integrity and if it's not an exact match, you'll get this error. Viri will cause this.
You could also try downloaded the demo from another machine to see if that works.
Yes, the way our software is licensed is that you download the demo and paste in the information sent when purchased.
