I see you found http://uk.mathworks.com/matlabcentral/answers/246457-the-specified-key-is-not-present-in-this-container-error-on-installing-support-packages-for-matlab but did you try the process listed there?

Thanks for your answer, yeah, I did. Seems to work. I just wanted to point out that it is not fixed in MATLAB 2015a as the mathwork support team has suggested in that link.
