Hello, I'm facing a problem: at school we use Windows Server 2008R2 and Windows 7 clients. Pupils can log-in with their own account. BUT when I plug-in the Arduino Uno the computer can't install the 64bit driver because of missing admin-rights (can I deploy the driver?). Second problem is that if I start the Arduino-IDE pupils can't choose the port the Uno is connected to. If I start the IDE with admin-rights I can choose the right port, but then pupils can't save their projects in their home-directories. Any ideas? Thank you very much for helping me.
