Hi Jon,
I read the document. I had already registered on the Xilinx website. I went through the same license acquiring procedure for Vivado. The product showed up in the license table. However, for the ISE 14.7, the webpack did not show up. The license table was completely blank.
I think that the ISE14.7 is not supported by Xilinx anymore. I will return the Nexys3 to the seller, NKC Electronics.
Thank you,
Frank
