Reinstallation of Matlab version 2012a

I am trying to re install Matlab on my PC. I downlaoded the software from my school website. The program has been downloading for the past four hours and is only half way done downloading. Is there a way to speed up this process. This is the second time I have tried downloading the matlab 2012a version today. The first time it said 64 bit didnt support my computer( i didnt choose the 64 bit option when initially installing) but i have had this version previously on my computer and there is enough free space to install the program

I suggest you contact Support.

If possible, you may want to limit the Toolbox downloads to the ones you need.
