Thanks Drayke,
Sorry my mistake Blender only as an exe from the blender foundation and a exe. I thought that msi worked better on windows networks, but it obviously doesnt!
If they can browse the network drives, does this allow them to read the files in the network drives? I don't have access to the install myself to test this unfortunately.
And, I see you are UK based and at a school that uses blender, you might be interested in the 3Dami.org free summer school
