Not sure if this is the right place to post. I'm looking for a place to buy a HD Architect version between 2020 and 2025 - any insight were I could purchase a legitimate version. I've been using HD since 2006 and currently have the 2019 version for my own small home renos (so I can see before I demo) so have zero ability to justify subscription. Are there alternative programs that one would suggest if it's not possible to buy an older version?
