Unexpected error during installation

I have a student license and I'm trying to install Matlab on a Mac OSX Yosemite (10.10.2 version). Since I don't know how to setup the connection setting so I chose to do it manually using a File Installation Key. After selecting the packages I want to install and before the installation itself begins, this message pops up:

The application encountered an unexpected error and needs to close. You may want to try re-installing your product(s). More information can be found at /var/folders/qm/fbpjtrt90jsfkzcjq7rrfml00000gq/T/mathworks_Usuario.log

I'd like to know why this keeps happening and how to get it finally installed (Mathworks Account or File Installation Key).

Thanks

Andrea - for installation issues, you may want to contact support directly at MATLAB support.

Then you will follow the same approach that Andrea did to get a solution. Doesn't that make sense? See Geoff's answer.
