Hello
Thanks for the answer but as i said my students and i have already requested licences at this place at the middle of March without any answer. I opened a support ticket the 21st of march where they said to send a message to Intel_Central_Licensing@intel.com. I sent a message to this address the 23rd of march without any answer. So i open a new support ticket the 27th of april and they said to write a question in this forum. And now in this forum, it is said that i have to do what i did at the beginning without any answer ...
Best regards
Eric
