I downloaded Intel Parallel Studio XE Professional for which the Intel Registration page says I have a valid non-commercial licence. I tried using the serial number after activating (both hardware numbers as there are two ports on the target computer), and also downloaded the licence file (with both hardware numbers). Nothing worked, either the licence was not stated as not being valid or the serial number.
The only thing I can think of is that my username on the computer is different from my email address/name, but this should not matter. Or there is some issue with firewalls.
All suggestions welcome.
