Nios II not installed

[Altera_Forum]

Dear all, 

Forgive me if I should have posted this in other place?   I have this CD-disc came along when I bought the DE0-NANO FPGA, Cyclone IV E.   Please refer to the attached files.   In 2.jpg, it is stated that the free package includes "Nios II processor".   However, in 1.jpg, I could not find the "Nios II processor" component to be installed.   I tried several attempts, I could use Quartus II with no problem however, I could not locate Nios II IDE.   I also tried downloading the Nios II IDE installation file from this link (https://www.altera.com/support/software/download/nios2/dnl-nios2.jsp), however it could not be installed, it keeps prompting me that I need to have Quartus before installing Nios II, I am pretty sure I have Quartus II since I have used Quartus II and run the simulation for quite a number of times.   I am using Wondow 7, 64bit.   Please let me know:   1. how could I check if I have Nios II IDE although i don't think it is there?   2. How could I get the installation file that work along with this version of Quartus II 10.1?   Hope to hear you soon, thank you very much.   --

That only means the Nios hardware component is part of Quartus package. 

But in order to develop a Nios application you need the Embedded Design Suite (EDS) which in older Quartus releases was a separate package .
