Hello, I'm unable to download Quartus 9.1 (32 & 64-bit) web edition, need this for ACEX 1K50 FPGA.

Hi,

I am sorry for the delay in response as I was out of office for the past 5 days. Can you try to download using this link https://www.intel.com/content/www/us/en/programmable/bin/get-download?swcode=WWW-SWD-QII-SE-91-PC&l=en?

Thanks.
