Unable to download CUDA 7.5 toolkit

I am trying to download CUDA toolkit 7.5 from https://developer.nvidia.com/cuda-75-downloads-archive .When I click on the links for ubuntu 15.04 and related x86_64 files,nothing happens. Has support for CUDA toolkit 7.5 ended ? I am using a code that requires CUDA 7.5 toolkit.Please guide.

Seems to work fine right now, from California. I tried Linux / x86_64 / Ubuntu / 15.04 / runfile(local). This is a 1.1 GB file.

From what location are you trying to download? Does it not work at all (i.e. progress bar shows 0%), or does the download fail part of the way through?

Still the link does not download anything.I am accessing it from India.
