Office, Microsoft

Note that this probably is the usual best quality productBut is a pay product

Current Versions of Microsoft are various versions of 
[URL] [Wikipedia] Office 2019, which is a lifetime license and typically has media for outside the internet

DO NOT confuse the subscription version with the lifetime version, it will screw you up.
