Acronis Snap Deploy questions

I just downloaded the demo for the snap deploy and when I went to install it on a windows server 2003 and the install failed saying

Anybody ever see this problem? Snap deploy has not been installed on this machine previously.

Secondly, is snap deploy the correct image software to use. We want to create a clean OS image that can be reloaded to test software. We will have many different versions of OS's that need to be loaded. XP Pro, XP Home, 2k, etc. and we would like to keep them located on one server ready to be loaded onto different machines.

Thanks
