I am using ubuntu 14.04 LTS 64 bit os. I tried to install Quartus prime pro 16.0 by running .sh(dev1_setup_pro) file, But I got error message as "You dont have Quartus Prime software installed in /home/super/altera/16.0. You need to have Quartus Prime software installed in that directory before installing this software". I have attached snap of error. Why I am getting this error and what is the solution for this.
