Matlab 2015a on Yosemite OSX Install Problem

I'm trying to install Matlab 2015a Student Version on a Mac running Yosemite OS X. I have had no problem downloading and installing and activating 2013a, 2014a & 2015b student versions from the licence centre, but I have code which currently only runs on 2015a or 2014b (due to the changes in Fortran compiler compatibility it doesn't run on 2015b). Every time I try to run the 2015a installer and activate I get the error: "There are no products available to install from this location. You may need to download the appropriate products from our web-site (www.mathworks.com)." This wasn't a problem for 2015b or earlier versions with the same procedure, so can someone explain what's going on here or a solution? Thanks!!
