Hi everyone,

Recently I have reinstalled my operative system (Windows 11) and since then i couldn’t open OpticStudio because when it requests me the license key, it says that has been already used.

I used that key months ago, before reinstalling the operative system and now i don’t know how what to do (the license is still valid).

I have an Academic License, i study in University of Bologna (UniBo).

Does anyone know how to solve this issue?
