Quartus Version: 11.1 Service Pack 2.11

Hello,

I am setting up the tools to re-compile a previous project. The project was compiled, according to the SOF/POF/JIC header in the project folder, by using Quartus II 64-Bit Programmer Version 11.1 Build 259 01/25/2012 Service Pack 2.11 SJ Full Version. I downloaded the Quartus II 64 bit version 11.1, but cannot find the Service Pack 2.11 (There is only Service Pack 2 on the Altera's download page). Could you tell me where I can obtain the Service Pack 2.11?

Best Regards,
