Welcome to INTEL forum. The Altera Cyclone IV GX Transceiver Starter Kit has been put EOL (end of life). Regrettably, we don’t keep the dev.kit installation file. Apologize for inconvenience happen.
We have not heard from you and I hope that my last note clears up this matter. I will now transition this thread to community support. If you have a new question, feel free to open a new thread to get the support from Intel experts. Otherwise, the community users will continue to help you on this thread. Thank you.
