Good evening, I'm coming to you because Twitter's customer service just happens to be a ghost, I explain my problem: I bought a Parallels Desktop 17 with upgrade license (Parallels Desktop 14) for 49 € which I managed to activate successfully on my Mac, except my Mac had a problem and had to take some back a new one, the problem is when I put the license of v17 then that of v14 it does not work, because already assigned and even by checking "Activate it on this Mac" it does not work, it returns to me " This license key is associated with another Parallels account. Please log in using that account, then try again. ". What to do ?
