Emmm. I did some digging and found the link. You'll need the Intel C++ Composer XE for Windows, the link ishttp://software.intel.com/en-us/articles/intel-c-composer-xe-purchase/
The Intel C++ Composer XE for Windows comes with the Intel C++ compiler, Intel IPP, Intel TBB libs, and Intel MKL libs.
We do notoffer the Intel C++ compileronly pkg any more.
You said you have an old license,check it to see if it's cheaper to just renew the support service.
Sorry for the delayed response.
The Intel C++ compiler from Intel Parallel Composer is a light weight compiler. It does not have the full compiler optimization functionalities as the one in Intel C++ Composer XE product pkg.
Before you buy it, try both with eval. See if the Intel Parallel Composer 2011 is good enough for you.
