Hi there @marlen,
It is normally located within the text of the email you would have recieved, that also had the download & installation instructions......do you still have that?
EDIT: I've just seen a new post by @LauraWatson about this, here..... https://community.plm.automation.siemens.com/t5/Solid-Edge-Student-Edition-Forum/License-code-no-lon...

We changed the way we license the academic version back on February 2nd. If you downloaded the install file before that date you will need to re-download the install file to get the updated version with the updated license file.
