Thanks Sam, after some research, we will have 4 classrooms of 10 computers with the lan installation as well as around 40 laptops with the offline installation. I can live with the upgrading on so many computers but how do you find out when updates are available or required? I'm just trying to work out the best solution for installation.
If there are no notifications, I may consider just rolling everything out as the offline clickonce test player, so they get updates automatically and everyone follows the same userguide
