OK, I've bought numerous versions of Parallels Desktop over the years, I just bought Parallels 18 a couple of weeks back. However, this thread is on an old version issue I am facing. I am trying to install Parallels 11 on an older Mac, for which I have bought a licence a few years ago. The license is listed I'm by account, under "Legacy Licenses" tab. However, as soon as I install Parallels Desktop 11, from Parallels' own servers (https://kb.parallels.com/5802), and installing the software, activation fails with some "check your internet connection" error. Chat support claims that they do not provide support for this older version, while at the same time they insist that they do not block me from using an older version. What's going on here?
