Development support for Stratix II and IV devices

Well, you can go here:

https://www.intel.com/content/www/us/en/collections/products/fpga/software/downloads.html?edition=lite&platform=windows&s=Newest

to the FPGA download page.

Then in the lower left column, select the device family you want (ie, Stratix II or IV), and it will filter Quartus versions that apply.

So for Stratix II, Quartus Subscription 13.0sp1 is the only supported version.

For Stratix IV, the above version will also work, as well as the most recent Quartus Standard 21.1 version.

As to programmers, I like the Terasic USB Blaster. There is also the Terasic USB Blaster II that supports high speed operation for more $$.
Go to www.terasic.com and look under 'products' and 'usb blaster cable'.
