Ran into this problem. I own an old (2009) version of Quickbooks Mac. Old computer. Simple standalone setup, I don't need anything other than what I had. I had a hard drive issue and had to re-install my OS and reinstalled the Quickbooks, which I did from my original retail CD that I purchased and physically own along with the box, documentation and CD key. Of course it would not register. I spent half a day on the phone with tech support and they somehow convinced me to buy Quickbooks Online, which is completely unusable for what I need to do.

I just want to use the software THAT I PURCHASED AND LEGALLY OWN. It is absolutely CRIMINAL to lock someone out of retail software that they physically own. I smell class-action lawsuit ...
