Installing Creo3 on a school network.

Hi- Does anyone have experience of installing Creo3 on a school network. We've looked at Creo3 as a standalone install but the IT technicians want to copy across the network rather than on each machine.

I'm sure other schools must do this- any advice/help gratefully received!

ALSO can Creo2 and Creo3 exist on the same machine?

AND could not create "mold" parts in Creo3 -is there a software switch I need to set?

Scratching my head so hard the kids are starting to complain
