Support Packages (Arduino) on Network Installed PCs doesn't work other than Administrator

I installed the Arduino Support Package as Administrator and it works fine. When other users in my Lab log in and try it it won't work. I've been working with some old fixes but they don't work. Does r2015b solve this multi-user issue with support packages so that when the Admin installs them all user can use the package?? Please! This really hurts my academic instruction of matlab/simulink because I cannot use Arduinos with it. Jason
