As other indicated, there are several hoops to jump through, but all worked in the end. Once you "purchase" for $0 from third party site, you have to wait for them to send you the activation code via email. After that, I had turn off my Smart App Control to get the Setup to install - which is kind of bummer as you can't turn it back on. Otherwise, Adobe is working great to edit PDFs. The black Adobe logo is kind of weird, but ok, but I was able to login to my Adobe account via the software and update it as well...so all seems to be working correctly.
