Can't Install Intel C++ Composer XE for Linux

[noloader]

I'm trying to install Intel® C++ Composer XE for Linux (composer_xe_2013_sp1.0.080). It is the academic version (), and was downloaded about 1 hour ago.

I try to accept defaults before the actual install, but the installation program forces me to chose and installation directory. At the prompt, I enter "/opt", or "/opt/", or "/opt/intel", or "/opt/intel/". The installation program simply loops back around as if I did not enter anything.

I've run the program through `sudo`, and even dropped into a root terminal with `su -` to ensure sudo was not dropping too soon.

How do I fix this? Its incredibly annoying behavior.

Thanks in advance.
