I got several versions, none of them said leopard, but it wouldn’t work in any version.
It worked fine in a clean install, i guess it had a problem with my legal install i had, and updated, and then we needed the 2 serials for other computers, so mine got deactivated. So i guess the older version was pissed. I never found all the fles it puts elsewhere, AppZapper got them though. Works fine now.
