I just installed Matlab R2012a on my OS X Lion machine. When I start up targetinstaller, I get to choose between installing from internet or from folder, but none works.
I have tried downloading the Simulink Support Package for LEGO Mindstorms and install from a folder containing the zip but it just said it couldn't find any support package.
Installing from the internet just stop with a buggy-looking window (see linked screenshot). My friend running OS X also has the same issue (I use XQuarts and he uses X11). Any ideas what's going on?
