Hi folks, I've recently purchased an Office 2019 Home & Small Business through HUP program (still available but not for long, sadly). That version works on a Mac, but is supposed to works on Windows 10 too. I found an iso of that program that seems legit (downloaded from M$), and installs fine. Only four producs are offered (Word, Excel, Outlook & PowerPoint), since this is an home edition. However, when I want to activate it, I'm prompted to create a M$ account after entering key (which I don't want). I try then to enter key manually using ospp.vbs /inpkey:xxx, and I've got an 'invalid key' message... BTW, no issues so far to enter a key for Pro Plus version (another key, and another iso, of course). Is someone has some tips, this is very welcome! Thanks alot!
