Install using File Installation key

I have a problem with downloading matlab to my computer , since my university allows us using matlab, it should be without problem, but when i create my account and try to download it , some request appeared : "Install using File Installation key". I dont know what does it mean, as all my colleagues have not anything like this to write there, and university does not give us any key
