I downloaded a free Student Edition from this link. It worked on Windows 10.
But I now use a new computer with Windows 10 Pro, so I transferred the licence on the old PC in the help menu.
I think I have to download a launcher on the new PC but how ?! I tried to copy the launcher from the old PC but it doesn't work on the new one, and i can't download the launcher without requesting a new key (because I have to fill in the form in the link above).
Please help !
