Successfully installation of office 1026 and 2019
I bought 2 licenses, 1 office 2016 and 1 office 2019 via PayPal. Licenses were valid, I registered to Microsoft and everything were perfect. 4 stars are because the download links were not valid, so I had to search to Internet to download offices (2016 was more difficult), but at the end of the day both of them were installed and registered.
