there were 2 active installs. i'm not sure where one of them is [...] I think it was on a Mac Mini i have in a drawer somewhere....
When you activate an Isadora 3 Perpetual, Subscription, or Rental License, the dialog gives you an optional field for a name at the bottom. If you put a name in there, it'll show up in the Online License Portal too (which makes it handy for choosing which computer to remotely deactivate your license on).
i've deactivated it remotely. Awesome! I was not aware this was possible.
It's super handy. It also means if a computer breaks, needs to have the data wiped, gets stolen/destroyed, etc, you can go on the Online License Portal and deactivate your license on that computer remotely and then immediately activate your Isadora 3 Perpetual, Subscription, or Rental License on a different computer hassle-free :)
