How can I download an old version of Intel Fortran Compiler? I have subscription only in 2020 but I used in university in 2008 Linux version. How can I download and install it?
For a version that old you'll need to contact Intel Support (and have current support). Why would you want such an old version? It probably would not install on recent Linux distros.
